Description

[Detailed Description of the Invention] The present invention relates to a rotating mesh barrel for a tea steamer that steams tea leaves.

The rotating mesh barrel of a tea steamer is made of a cylindrical frame made of front and rear ring members and several pieces of aggregate, and a wire mesh with a lattice pattern stretched inside it. I was wearing it.

That is, as shown in Figure 1, a flat washer b with a thickness of a few tenths of a millimeter is placed on the rivet head a side of the rivet, and this is inserted from the wire mesh c side into the hole e of the frame d through the mesh, and then , as shown in Fig. 2, the calling jig f
The bolts were hammered to make them stick together, and finally the tips of the rivets g protruding from the frame d were crushed with a hammer or the like.

However, according to this conventional method of fastening, if the crushing of the rivets is weak, the rivets loosen and a gap is created between the flat washer and the wire mesh, and if the crushing is strong, the rivet heads are buried in the mesh, and the flat washer It transforms into a bowl shape as shown by the dashed line.

If a gap occurs between the flat washer and the wire mesh, or if the flat washer itself deforms into a bowl shape, the leaf stems that are being steamed will get caught in the gap, damaging or cutting the leaf surface and deteriorating its quality.

Moreover, not only is it troublesome to clean after use, but it also promotes the buildup of tea stains, corrodes the thin flat washer, and causes the wire mesh to peel off over many years of use.

The present invention was developed in view of the current situation, and involves inserting flat 〓-shaped stop needles into each of the corresponding meshes of the wire mesh into each of the many stop holes drilled at appropriate locations on the frame. By bending both bent sides of the needle and stretching the wire mesh, the inner circumferential surface of the rotating mesh barrel is finished smoothly, and there is no catching or cut leaves.
Furthermore, the present invention provides a rotating mesh cylinder whose wire mesh does not peel off even during long-term use.

Next, the present invention will be described with reference to illustrated embodiments.

1 is a frame that is assembled into a cylindrical shape with front and rear ring members 2 and 3 made of flat plates in a ring shape, a plurality of flat steel aggregates 4, and a reinforcing ring body 5 made of a round bar in a ring shape; Reference numeral 6 denotes a wire mesh with a lattice pattern, which is stretched inside the frame 1 with its vertical mesh aligned in the front-rear direction of the frame 1.

Together, these constitute the rotating mesh barrel of the tea steamer.

Reference numeral 7 indicates a stopper for tensioning the wire mesh 6 onto the frame 1, and 8 indicates a stopper hole thereof.

A large number of fastening holes 8 are drilled at appropriate locations in the front-rear direction of each member 2, 3, and 4 of the frame 1, and are spaced apart by several mesh pitches of the wire mesh 6, 20 mm apart in this embodiment. It also consists of two pores 8' and 8'.

Stop needle 7 has a length of about 50 mm and a wire diameter of about 2 before installation.
A wire material with a half-moon shape in cross section is about mm, and its middle side 7a
The left and right sides 15 mm each are bent toward the flat wall side with a half-moon cross section so that the width is about 20 mm, and the ends 7c of the bent sides 7b on both the left and right sides are further bent slightly inward to form a planar approximately 〓 shape. It shows that.

As shown in FIG.
into each of the pores 8', and then the wire mesh 6
After passing through the mesh, the intermediate side 7a is struck with a hammer or the like to curve the double-bent side 7b from its base to match the recess 9, and then, as shown in Fig. 6, a flat hitting platform is At the top, the middle side 7a is further hammered, and both bent sides 7b are bent inwardly into a hairpin shape to be attached.

At this time, only one or several wires 11 constituting the horizontal mesh of the wire mesh 6 are surrounded between the intermediate side 7a and both bent sides 7b of the stop pin 7, which are bent into a hairpin shape. Therefore, this part does not become thick.

In other words, like riveting using conventional flat washers,
It can be made extremely thinner than when the thickness of the wires intersecting in the vertical and horizontal directions of the wire mesh, the thickness of the flat washer, and the thickness of the rivet head are added together.

Furthermore, since no plate-shaped items such as flat washers are used, there is no knife-like edge effect on the leaves and stems.

For this reason, there is no risk of the leaf stems getting caught, damaging or cutting the leaf surface, and causing quality deterioration.

Moreover, in this embodiment, the stop needle is made of a wire material having a substantially half-moon cross section, the flat surface is on the inside and the curved surface is on the outside, and both bent sides of the stop needle are bent inward to form a hairpin shape. As a result, the needles are in surface contact with the frame and the wire mesh, and can be firmly attached.

On the other hand, since the outside of the bent clasp has a curved surface, the inner circumferential surface of the rotating mesh barrel is very smooth.

In the present invention, a large number of stop holes consisting of two pores separated by several mesh pitches in the direction of the mesh of the wire mesh to be stretched are bored at appropriate locations on the frame, and each stop hole has a corresponding hole in the wire mesh. We decided to insert a flat 〓-shaped stop pin through the mesh, bend both bent sides of the stop pin, and stretch the wire mesh inside the frame to construct the rotating mesh barrel of the tea steamer. The inner circumferential surface of the rotating net barrel can be made very smooth, and catching of leaves and stems and cut leaves can be eliminated.

Moreover, since it can be firmly fixed, it can withstand long-term use.
