Coffee filter structure

This creation relates to a filter structure, and more particularly to a coffee filter structure for follicular coffee.

According to the method of making coffee at home, there are three types of instant type, bubble type and cooking type. Instant coffee, in general, is a powder containing three components of coffee, creamer and sugar (commonly known as three-in-one coffee) and then brewed into a cup, which is less able to bring out the mellowness of the coffee. Cooking coffee is brewed by coffee machine. The coffee machine has great difference in price according to the function and cooking professional degree. The taste of the brewed coffee is different, and the coffee machine is bulky and takes up space. There are a lot of procedures, long cooking time, and troublesome cleaning after use, so some people don't want to use the coffee machine.

Follicular coffee is an option between coffee machine and instant coffee. It provides a cone-shaped funnel-shaped filter with an inner space. The filter has a plurality of meshes around the periphery, and the filter crosses the filter. Place it on the cup mouth of the cup, then put the coffee powder into the inner space of the filter, then pour the boiled boiling water into the filter, so that the hot water slowly passes through the coffee powder, and the hot water flows out of the mesh of the body to extract the coffee. Drop the droplet into the cup.

For example, the new patent No. M459821, "Applicable to filter screen structure for filtering coffee" is a conventional filter structure which is combined with a ring piece at the end of a filter screen, and is filtered. The outer side of the net is provided with a plurality of ribs, and the ring piece is provided with a reinforcing rod, and the bottom of the filter net is further provided with a positioning piece (bottom positioning piece) for integration with each of the ribs, by the filter net and each The rib and the ring piece are combined to achieve the effect of being less susceptible to dent deformation.

However, in the conventional filter structure, the plurality of ribs are separate members, the lower end is connected by a joint member, and the bottom of the filter screen is further provided with a positioning piece combined with the rib, and the filter screen and the rib piece thereof. The upper end and the ring piece are fixed by the crimping method, so the overall structure is complicated, the assembly operation is cumbersome, the manufacturing cost is high, and the bottom dead angle is large, the cleaning is inconvenient, the dirt is not easily concealed, and the hygiene is doubtful.

In view of the conventional filter structure, the creator has the disadvantages of complicated structure, cumbersome assembly action and difficulty in cleaning at the bottom. It is the idea of designing and testing, and after many modifications and improvements, Launched this creation.

The present invention provides a coffee filter structure comprising: a support frame having a bottom cap and a plurality of ribs radially extending from the periphery of the bottom cap to form a tapered shape, and the ribs are formed in a rib shape Forming a channel; a filter screen is a large upper and lower cone, and a plurality of ribs and a bottom cap of the support frame are combined and fixed; a ring frame has a horizontal ring piece, and the ring piece has a ring shape A splicing piece is integrally formed on the rim, and the splicing piece is sleeved on the inner surface of the filter net to be fixed and fixed; and a set of rings is sleeved and fixed on the outer side of the upper end of the support frame.

The main purpose of the present invention is to provide a coffee filter structure which is simple in structure, easy to assemble, low in manufacturing cost, low in dead angle at the bottom, convenient in cleaning, and difficult to cause dirt and dirt, and can ensure the use of sanitary safety.

Referring to the first, second and third figures, the coffee filter structure comprises: a support frame 10, a filter screen 20, a ring frame 30 and a set of rings 40.

The support frame 10 has a bottom cap 11 and a plurality of ribs 12 radially extending from the periphery of the bottom cap 11 to form a tapered shape, and the ribs 12 are formed in a curved shape, and the ribs 12 are arranged in an arc shape. Forming, a channel 13 is formed between each of the fins 12.

The filter screen 20 is a large upper and lower cone, and is sleeved on the inner surface of the plurality of ribs 12 and the bottom cap 11 of the support frame 10, and is fixed and fixed by spot welding to make the filter screen 20 and the ribs 12 and the bottom. The inner surface of the cap 11 is fitted.

The ring frame 30 has a horizontal ring piece 31. The inner edge of the ring piece 31 extends integrally to form a tapered taper ring 32. The bond piece 32 is sleeved on the inner surface of the upper end of the screen 20. The screen 20 and the ribs 12 of the support frame 10 are fixed in a spot welding manner.

The collar 40 is an annular sheet having a tapered downward taper, sleeved on the outer side of the upper end of the support frame 10, and fixedly coupled to the upper end of the support frame 10 by spot welding.

The coffee filter structure of the present invention, when used, as shown in the fourth figure, the horizontal ring piece 31 of the ring frame 30 is placed over the opening of a container 60, so that the filter screen 20 is placed in the container 60, in the filter screen 20. The powdered coffee powder is placed inside, and then the boiled boiling water is poured into the sieve 20, so that the hot water is slowly passed through the coffee powder, and the coffee liquid is extracted through the sieve 20 and the ribs 12 of the support frame 10. The channel 13 is dropped into the container 60 to complete the follicular coffee.

In addition, the created coffee filter structure may also include a base 50 as shown in the fifth and sixth figures. The base 50 is in the shape of a disk, and may of course be designed in other shapes. The center of the base 50 is disposed. There is a through hole 51. The inner diameter of the through hole 51 is distributed in a radial shape to three fan-shaped segments 52 having a flow guiding surface. Each of the segments 52 is disposed at the center of the base 50 to form a joint portion 53, and the segments 52 are formed with drops. The drop hole 54 is detachably combined with the lower end of the bottom cap of the support frame 10, and the base 50 can be combined with the support frame 10 or separated from the support frame 10. This embodiment The joint portion 53 is a screw hole, and a stud 111 is disposed at a lower end of the bottom cap 11 of the support frame 10. The combination portion 53 of the screw hole is screwed with the stud 111 to form a detachable combination.

In use, as shown in the seventh figure, the base 50 is placed over the opening of a container 60a, so that the screen 20 is placed above the container 60a, and the powdered coffee powder is placed inside the screen 20, and then The boiled boiling water is poured into the sieve 20, and the hot water is slowly passed through the coffee powder, and the coffee liquid is extracted through the filter screen 20, the passage 13 between the ribs 12 of the support frame 10, and the drip hole 54 of the base 50, and drops. Into the container 60a, the follicular coffee is completed.

Furthermore, as shown in the eighth embodiment, the joint portion 53 of the base 50 and the lower end of the bottom cap of the support frame 10 are integrally fixed and integrated. In this embodiment, the joint portion 53 is directly connected to the support. The lower end of the bottom cap 11 of the frame 10 is welded and joined, and may also be combined by riveting.

From the structure of the above specific embodiment, the following benefits can be obtained: In the coffee filter structure of the present invention, the plurality of ribs 12 of the support frame 10 are integrally formed with the bottom cap 11. The filter screen 20 is directly sleeved on the inner surface of the plurality of ribs 12 and the bottom cap 11 of the support frame 10, and the upper end of the support frame 10 is fixed. The outer sleeve is sleeved and fixed, the overall structure is simple, the assembly action is easy, the manufacturing cost is low, the bottom dead angle is small, the cleaning is convenient, the dirt is not easily caused, and the sanitary safety of the use is ensured, and the market competitiveness is improved.

In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress. When complying with the provisions of the Patent Law, it proposes a new type of patent application according to law. The census review committee granted legal patent rights and was praying.
