Description

Drip coffee brewing unit and drip coffee brewing kit

technical field

The invention relates to the field of daily necessities, in particular to a drip coffee brewing device and a drip coffee brewing set.

Background technique

As a symbolic drink of modern life taste, coffee has gradually entered people's daily work, study and life. People soak a cup of rich and mellow coffee in their spare time, which will not only greatly improve their spirits, but also allow people to slowly enjoy the infinite relaxation and beauty of their spare time.

With the continuous improvement of people's requirements for coffee drinks, more and more people think that the coffee drinks after cooling down for a long time are more delicious, and the longer the cooling process, for example, the coffee drinks that will be brewed After cooling overnight, the essence of coffee can be obtained more. When you need to drink cold coffee, pour coffee powder into a specific brewing device, and then use cold water to brew the coffee powder in the brewing device to get cold coffee, and then these people will pour the cold coffee in the brewing device Pour slowly into a coffee mug and drink.

These people usually think that after one night of cold storage and dripping of coffee in a low temperature state, the cold coffee dripping into the coffee cup is the ultimate coffee essence and has more benefits for people to drink. This puts forward higher requirements to the current coffee brewing device: the existing coffee brewing device needs to fully dissolve the coffee powder into the cold water of the brewing device, and the cold coffee brewed by cold water needs to be extremely slow. Through a longer dripping process to drip into the coffee, so as to get the cold coffee that people like, so that the user can drink the final coffee essence and enjoy the deliciousness brought by the cold coffee. However, existing coffee brewing devices cannot meet people's above-mentioned high-quality requirements for cold coffee.

Contents of the invention

The primary technical problem to be solved by the present invention is to provide a drip coffee brewing device for the above-mentioned prior art. The drip coffee brewing device can satisfy the user's need to adjust the drip time of coffee to adjust the drip time of cold coffee to obtain cold coffee, thereby satisfying the user's demand for high-quality drinking of cold coffee.

The further technical problem to be solved by the present invention is to provide a drip coffee brewing set for the above-mentioned prior art. Users can drink the cold coffee they need by cooperating with the drip coffee brewing device and coffee cup in the kit.

The technical solution adopted by the present invention to solve the above-mentioned primary technical problems is: drip coffee brewing device, which is characterized in that it includes a funnel with an open end and a drip bowl with a chamber, the head end of the funnel has a drip hole, and the end of the funnel The tightening disc is rotatably fastened, and the tightening disc has a housing cavity, and a protruding structure is arranged in the housing cavity, and a diversion hole is located at the bottom of the housing cavity; The hole and the adapter plate, the adapter plate is provided with an opening for the entry of the raised structure; the tightening plate and the adapter plate can be rotatably connected to adjust the gap between the raised structure entering the opening and the opening .

In order to realize the limit adjustment of the rotation of the screw-on disc relative to the drip bowl, to facilitate the user to control the dripping speed of hot coffee and to adjust the drip time of cold coffee, further, there is a gear bar on the upper edge of the inner wall of the screw-in disc, The outer wall of the bottom of the drip bowl has anti-rotation ribs that cooperate with the gear bar, so as to realize the limit adjustment of the rotation of the tightening plate relative to the drip bowl through the gear bar and the anti-rotation ribs that cooperate with each other.

Since the raised structure 30 is in the shape of a cone, when the smaller upper end of the cone enters the opening 40 of the adapter disc 4, if the tightening disc 3 is rotated so that the upper end of the cone moves up in the opening 40, Then the part of the cone that enters the opening 40 will become larger, so that the gap between the cone and the opening 40 of the adapter plate 4 will become smaller, so that the dripping speed of the coffee in the drip bowl 2 will slow down. 2, the time for the coffee to drip will also change, so that there can be more time for the cold coffee to drip. Of course, as an optional matching structure, the outer wall of the protruding structure 30 has an external thread, and the inner wall of the opening 40 has an internal thread matching the external thread, thereby realizing that the protruding structure 30 can slowly rotate into into the opening 40 to realize the gradual adjustment of the interval between the protruding structure 30 and the opening 40 .

In order to place the removed funnel 1 , the drip coffee brewing device in this embodiment further includes a chassis 5 for fixing the funnel 1 . Specifically, the chassis 5 has a bearing chamber 50 into which the head end of the funnel 1 is placed, and an annular groove 51 is formed on the outer wall of the chassis 5 . The setting of the carrying chamber 50 can protect the head end of the funnel 1 and the filter screen 11 at the drip hole 10 from being damaged, and the annular groove 51 on the outer wall of the chassis can facilitate the user to hold the chassis.

Further, the bottom of the tightening disc 3 is connected with a threaded bottom ring 33, and a limit block 330 is arranged on the threaded bottom ring 33, and the end side wall of the funnel 1 has a limit groove 12 matching the limit block 330; the tightening disc 3 There is a thread ring rubber covering 8 on the outer wall of the adapter disc 4; an adapter disc rubber covering 9 is provided on the outer wall of the adapter plate 4; the accommodating cavity of the tightening plate 3 has a direction along the direction from the lower end of the raised structure to the upper end of the raised structure. Formed boss 34. Further, the drip coffee brewing device further includes an end cover 6 for covering the opening of the drip bowl, and the end cover 6 is provided with a through hole 60 . Wherein, an anti-slip structure 13 is provided on the outer wall of the funnel 1 .

In addition, referring to Fig. 11 and Fig. 12, this embodiment also provides a drip coffee brewing set, which has a coffee cup 7 and the drip coffee brewing device in this embodiment, the coffee The mouth of the cup 7 matches the funnel 1, so that the drip coffee brewing device is placed on the coffee cup through the funnel. Of course, for the convenience of drinking, the coffee cup 7 in this embodiment also has a straw 70 that can extend into the coffee cup.

In order to ensure that the temperature of the obtained coffee does not change significantly, the coffee cup 7 has an outer cup body 71, an inner cup body 72, and a sealing cover 73 for sealing the opening of the coffee cup; A sealed heat preservation cavity is formed between the inner wall of the cup body 71 and the outer wall of the inner cup body 72 . In addition, the opening of the coffee cup is provided with an external thread, and the outer side of the coffee cup opening is covered with a decorative ring 74, and the outer side of the decorative ring 74 is covered with a cup mouth thread ring 75, and there is a seal between the sealing cover 73 and the cup mouth thread ring 75.
