In order to further understand the functions produced by the coordination of the various components of the present invention, the use of technical means, and the expected effects, it will be explained as follows. It is believed that the present invention can be understood more deeply and specifically.

As shown in Figure 9 again, when brewing coffee, first lay the filter paper 1 above the top surface 112 of the coffee filter 10, pour hot water into the circular filter paper 1, and soak all the filter paper 1, then Pour an appropriate amount of ground coffee powder into the accommodating space 16 . The coffee filter 10 straddles the cup top 202 of the bottom cup 2 , and is extended in the chamber 201 by the limiting ring 13 , so that the coffee filter 10 is limited relative to the bottom cup 2 .

Then, place the water guide plate 20 across the top of the ring wall 12 of the coffee filter 10, and use the water retaining ring 24 and a plurality of water guide rings 27 respectively surrounding the bottom sections of the water guide holes 26 to extend to the container. In the space 16 , the water guide plate 20 is limited relative to the coffee filter 10 .

As shown by the arrow in FIG. 9 , when the operator pours hot water from the hijab button 23 of the water guide plate 20, the central area 213 gradually bulges from bottom to top and converges toward the axis L gradually, Hot water can be guided from the center corresponding to the axis L toward the surrounding wall 22, and evenly flow to the water guide grooves 25, the water guide grooves 25 produce the function of storing hot water, and the water guide holes 26 The ground coffee powder contained in the coffee filter 10 drips evenly, and the extracted coffee liquid drips into the chamber 201 through the filter holes 141, and utilizes the setting positions of the filter holes 141 and The way of arrangement can guide the coffee liquid to flow evenly and leak down. After the above-mentioned hot water passes through the water-guiding holes 26 , the arrangement of the water-guiding rings 27 can make the hot water pour into the accommodating space 16 intensively.

And as shown in FIG. 10 , during the above-mentioned coffee liquid extraction process, the filter paper 1 is supported by the rib sets 15 of the coffee filter 10 , so that the filter paper 1 and the long ribs 151 and short ribs 152 can Create a large number of gaps, which can increase the air convection between the filter paper 1 and the top surface 112, and use the long ribs 151 of two adjacent rib groups 15 to form a V-shaped convex arrangement, which can guide the water flow under the filter paper 1 to accelerate Flowing into the corresponding filter hole group 14 is beneficial to the smoothness of coffee extraction, that is to say, using the rib groups 15 to support the filter paper 1 and the 40 filter holes 141 can prevent the filter paper 1 from being completely tight after absorbing water. Attached to the top surface 112, the adsorption is too dense, resulting in slow water flow and blockage, which affects the flavor of the extracted coffee liquid.

In addition, the overall design of the water guide plate 20 can stabilize the flow of hot water, and at the same time, when the coffee is extracted in the coffee filter 10, the temperature of the hot water can be maintained, which helps Enhances the flavor of the brewed coffee. And utilize the design of this water retaining ring 24, can limit the range that hot water drips from these water guide holes 26.

Moreover, the overall structure of the present invention composed of the coffee filter 10 and the water guide plate 20 is simple, and the operation procedure of brewing coffee is quite convenient.

As shown in Fig. 11 to Fig. 13, it is the second embodiment of the present invention, and the difference from the first embodiment lies in the water guide pan 20', and the difference between the water guide pan 20' and the first embodiment only lies in omitting The hijab button and the water retaining ring are not provided, and the water guide grooves 25' are arranged radially around the central area 213', the shape of the water guide grooves 25' is oblong, and the arc at the outer end The arc is larger than the inner end. In addition, the water deflector 20' also includes four communication grooves 28' arranged at equal intervals around the axis L, and the communication grooves 28' are recessed from the bottom end surface 211' and communicated with the ring of the surrounding wall 22'. Zhou Mian.

As shown in Figure 13, when the water guide plate 20' is straddled on the top of the ring wall 12 of the coffee filter 10, and the water guide rings 27' around the bottom section of the water guide holes 26' are extended to the coffee filter 10 In the accommodating space 16 , the water guide plate 20 ′ can also be limited relative to the coffee filter 10 . When the operator pours the hot water from the central area 213' of the water guide plate 20', the hot water flows evenly from the central area 213' to the water guide grooves 25', and from the water guide holes 26' to the The ground coffee powder contained in the coffee filter 10 drips evenly. During the above process of extracting coffee, through the setting of the communication grooves 28', the air originally existing between the water guide plate 20' and the coffee filter 10 can be discharged (see the dot chain arrow in Figure 13 ), so that hot water can pass through these water guides more smoothly Hole 26'. Therefore, the function of the water guiding plate 20' is the same as that of the first embodiment.

It is worth mentioning that the coffee filter 10 can only be used in conjunction with the bottom cup part 2 alone, that is to say, the water guiding plate 20 can also be detached and used, and hot water can be directly injected into the coffee filter 10 to soak directly Extract coffee.

Furthermore, compared with the traditional funnel-shaped filter paper, the filter paper 1 used in conjunction with the present invention has a smaller area, which can reduce the amount of pulp used, save energy and reduce carbon.

To sum up, the novel coffee filter has a simple overall structure and is easy to operate, and can indeed achieve the purpose of the novel coffee filter.

But the above-mentioned person is only the embodiment of the present invention, and should not limit the scope of implementation of the present invention with this, and all simple equivalent changes and modifications made according to the patent scope of the present application and the content of the patent specification are still within the scope of the present invention. Within the scope covered by this patent.
