Abstract

The utility model relates to a filter. The filter comprises a sieve top cover and a sieve bottom cover, wherein the sieve top cover and the sieve bottom cover are buckled mutually. An annular disc is arranged at the connecting end of the sieve bottom cover which is connected with the sieve top cover in a buckling mode, a plurality of openings are annularly formed in the annular disc, and a locating flange surrounding the annular disc is arranged on the sieve top cover. Protruding ribs matched with the openings in size are directly formed inwards on the locating flange of the sieve top cover in a punching forming mode, and the protruding ribs correspond to the positions of the openings. Inclined steps are directly formed downwards on the left sides or the right sides of the positions of the openings of the annular disc. When the protruding ribs are inserted into the positions of the openings, the sieve top cover is rotated, the protruding ribs are connected on the inclined steps of the annular disc in a buckling mode, and therefore a locking structure of the sieve top cover to the sieve bottom cover is formed. The filter has the advantages of being simple in structure, and convenient to production, machine and use.

Description

Filter

Technical field

The utility model relates to a kind of filter of architecture advances, and especially a kind of making tea used tea strainer.

Background technology

The tea strainer of making tea is that tealeaves is packed in tea strainer, puts into cup or kettle, after making tea, directly takes out tea strainer, and tealeaves directly separates with millet paste.Because the tea strainer build is less, so its structure should be simple, otherwise, use extremely inconvenient; Existing tea strainer is generally to adopt disposable tea bag mode, the applicant improves existing tea strainer always, such as, the disclosed tea strainer of Chinese patent 201130057772.6 of the applicant application, but the fasteners that establish on its sieve bucket and screen cover employing two sides locks, complex structure, the production and processing operation is loaded down with trivial details, user's tealeaves that changes the outfit is extremely inconvenient, so, design novel tea strainer very necessary.

Summary of the invention

The purpose of this utility model is for the problems referred to above, provides that a kind of simple in structure, production and processing is convenient, easy to use making tea filter.

The purpose of this utility model is achieved in that sieve top cover and the sieve bottom that comprises mutual fastening, with be provided with ring-shaped discs on the sieve bottom link that is fastened and connected of sieve top cover, on ring-shaped discs, annular is furnished with several openings, and the sieve top cover is provided with the locating flange of outer encirclement ring-shaped discs; The direct punch forming inwardly of the locating flange of sieve top cover has the convex tendon of corresponding with aperture position and big or small adaptation; Ring-shaped discs in the left side of aperture position or/and the right side downwards directly punch forming oblique band is arranged; When inserting aperture position by the rotation of sieve top cover and snapped onto by convex tendon on the oblique band of ring-shaped discs, convex tendon consists of the sieve top cover to the locking mechanism of sieve bottom.

At least two respectively of the utility model, opening and convex tendon generally adopt three openings and three convex tendons.

The utility model can be provided with the filter connector on the sieve top cover.

The utility model has advantages of simple in structure, production and processing convenience, easy to use.

Following embodiment accompanying drawings is further described the utility model.

Description of drawings

Fig. 1 is the perspective view of an embodiment of the present utility model;

Fig. 2 is the perspective view of the bulk-breaking assembling of Fig. 1 embodiment;

Fig. 3 is the perspective view at convex tendon position partly cut-away state of Fig. 2.

In figure, 1, the sieve top cover; 2, sieve bottom; 3, ring-shaped discs; 4, opening; 5, locating flange; 6, convex tendon; 7,8, oblique band; 9, filter connector.

The specific embodiment

Referring to figs. 1 through Fig. 3, the present embodiment is that making tea of a kind of architecture advances used tea strainer, the sieve top cover 1 and the sieve bottom 2 that comprise mutual fastening, with be provided with ring-shaped discs 3 on the sieve bottom link that is fastened and connected of sieve top cover, on ring-shaped discs, annular is furnished with three openings 4, and the sieve top cover is provided with the locating flange 5 of outer encirclement ring-shaped discs; The direct punch forming inwardly of the locating flange of sieve top cover has three convex tendons 6 of corresponding with aperture position and big or small adaptation; Ring-shaped discs has oblique band 7,8 in left side and the right side direct punch forming downwards of aperture position; When inserting aperture position by anticlockwise or the right rotation of sieve top cover and snapped onto by convex tendon on the oblique band of ring-shaped discs, convex tendon consists of the sieve top cover to the locking mechanism of sieve bottom.

When the utility model used, after the tealeaves of packing into, the sieve top cover covered on the sieve bottom, and when convex tendon insertion aperture position, rotary screen top cover or sieve bottom snap onto on the oblique band of ring-shaped discs convex tendon, and the sieve top cover is locked with the sieve bottom; After making tea, reverse rotation sieve top cover, convex tendon breaks away from ring-shaped discs from aperture position, and the sieve top cover separates with the sieve bottom, pourable tealeaf residue.The utility model except being applicable to make tea, also can be used for soaking similar food product.

Claims (3)

1. a filter, comprise the sieve top cover (1) of mutual fastening and sieve bottom (2), it is characterized in that:

Be provided with ring-shaped discs (3) on the sieve bottom link that is fastened and connected of sieve top cover, on described ring-shaped discs, annular is furnished with several openings (4), described sieve top cover is provided with the locating flange (5) of the described ring-shaped discs of outer encirclement; The direct punch forming inwardly of the locating flange of described sieve top cover has the convex tendon (6) of and big or small adaptation corresponding with described aperture position; Described ring-shaped discs in the left side of aperture position or/and the right side downwards directly punch forming oblique band (7,8) is arranged; When inserting described aperture position by the rotation of sieve top cover and snapped onto by convex tendon on the oblique band of described ring-shaped discs, convex tendon consists of the sieve top cover to the locking mechanism of sieve bottom.

2. filter according to claim 1, is characterized in that: at least two respectively of described opening (4) and convex tendons (6).
