Description

Technical Field

[0001] The utility model relates to the field of self-service coffee machines, in particular to a self-service coffee machine capsule. Background Art

[0002] Self-service coffee machine capsules are a convenient and efficient coffee-making material. They work with the extraction device inside the self-service coffee machine to puncture the top and bottom of the capsule, and then inject hot water into the capsule to mix the hot water and the coffee powder inside the capsule. The mixture flows out through the punctured outlet at the bottom, thus making a cup of delicious coffee quickly. However, this method will cause the liquid to flow out directly through the outlet at the bottom when injected into the capsule, resulting in some coffee powder being left in the capsule, which not only has a poor mixing effect but also causes waste.

[0003] For example, the utility model patent (application number: 201620494702.4) discloses a "coffee capsule cup." Its specification discloses: "It comprises a cup body, a cup bottom, and a cup rim, with a transition section between the cup body and the cup rim. The cup body is provided with a PP layer, a glue layer, and an EVOH layer." This utility model, drawing on the design of the capsule housing chambers of most commercial capsule machines, sets the capsule cup diameter and cup rim width within a reasonable range. A transition section is provided between the cup body and the cup rim, and a retaining groove is formed between the cup body and the transition section. This prevents jamming when cups overlap, facilitating easy removal and making it ideal for assembly line production. This capsule cup incorporates a special EVOH material layer, resulting in excellent airtightness and lightness. A single capsule shell weighs less than 1g, making it easy for the capsule machine to pierce the bottom of the shell, ensuring a smooth coffee extraction process. Products filled with this series of capsule cups can be successfully marketed. The aforementioned patent serves to demonstrate the shortcomings of the existing technology.

[0004] Therefore, we make improvements to this and propose a self-service coffee machine capsule. Summary of the Invention

[0005] The purpose of the utility model is to address the problem that the existing coffee powder is left in the capsule, which not only has a poor mixing effect but also causes waste.

[0006] In order to achieve the above-mentioned purpose of the invention and improve the above-mentioned problem, the utility model provides a self-service coffee machine capsule, comprising a shell, two sealing members are provided inside the shell, a mounting opening is provided at the bottom end of the shell, a discharge member is provided inside the mounting opening, a blocking member is provided at the bottom end of the shell, a first mixing member is provided outside the blocking member, a second mixing member is provided outside the first mixing member, and ten puncturing members are provided outside the second mixing member.

[0007] As a preferred technical solution of the present application, the ten puncture members include a mounting block fixed to the bottom end of the inner portion of the shell, and a plurality of puncture blocks are fixed to the top end of the mounting block.

[0008] As the preferred technical solution of this application, the discharging part includes a discharging cylinder fixed inside the mounting port, a blocking block is fixed on the top of the discharging cylinder, and a plurality of discharging grooves are opened on the top of the blocking block, and the interior of the discharging groove is connected to the interior of the discharging cylinder.

[0009] As a preferred technical solution of the present application, the blocking member includes a No. 1 blocking ring located outside the blocking block, the No. 1 blocking ring is fixedly connected to the bottom end inside the shell, and the top of the No. 1 blocking ring is provided with several discharge ports.

[0010] As a preferred technical solution of the present application, the No. 1 mixing element includes a No. 2 blocking ring located outside the No. 1 blocking ring, and a feed trough is provided at the top of the No. 2 blocking ring, and the feed trough at the top of the No. 2 blocking ring is inclined.

[0011] As the preferred technical solution of the present application, the No. 2 mixing element includes a No. 3 blocking ring located outside the No. 2 blocking ring. The top of the No. 3 blocking ring is also provided with several material troughs. The material troughs at the top of the No. 3 blocking ring are inclined, and the inclination angle of the material trough at the top of the No. 3 blocking ring is opposite to that of the material trough at the top of the No. 2 blocking ring.

[0012] As a preferred technical solution of the present application, the two sealing members include two sealing membranes fixed inside the housing, and the sealing membrane located at the bottom is located above the ten mounting blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the scheme of this application:

[0015] 1. The puncture point can be precisely controlled by the puncture element, so that the liquid always enters the space between the second mixing element, the first mixing element, and the blocking element from the periphery. The first and second mixing elements assist in mixing, resulting in more uniform mixing and preventing coffee powder from being left inside the shell, which causes waste. This solves the problem of coffee powder being left inside the capsule in the prior art, resulting in poor mixing effect and waste.

[0016] 2. By setting up the No. 1 mixing element and the No. 2 mixing element, the mixture flows and mixes between the No. 1 mixing element and the No. 2 mixing element, and then enters the No. 2 mixing element and the blocking element for secondary flow mixing, thereby achieving a better mixing effect and solving the problem in the prior art that the liquid passes through the outlet quickly during mixing, resulting in poor mixing.

[0024] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] Example 1

[0029] Please refer to Figure 1 、 Figure 2 and Figure 3 A self-service coffee machine capsule comprises a shell 1, two sealing members are provided inside the shell 1, a mounting port is provided at the bottom end of the shell 1, a discharging member is provided inside the mounting port, a blocking member is provided at the bottom end of the shell 1, a mixing member No. 1 is provided outside the blocking member, a mixing member No. 2 is provided outside the mixing member No. 1, and the mixing effect is increased by the blocking member, the mixing member No. 1 and the mixing member No. 2. Ten puncturing members are provided outside the mixing member No. 2, and the ten puncturing members can appropriately puncture more areas to improve the flow efficiency. The puncturing members are used to puncture the sealing member at the bottom, thereby accurately controlling the puncture point so that the liquid always enters the mixing member No. 2, the mixing member No. 1 and the blocking member in sequence from the periphery.

[0030] Further, such as Figure 3 and Figure 4 As shown, the ten piercing members include a mounting block 501 fixed to the bottom end of the inner portion of the housing 1 , and a plurality of piercing blocks 502 are fixed to the top end of the mounting block 501 , through which the top end of the piercing block 502 is used to pierce the seal at the bottom end.

[0031] Further, such as Figure 2 and Figure 3 As shown, the discharge part includes a discharge barrel 302 fixed inside the mounting port, a blocking block 301 is fixed at the top of the discharge barrel 302, and a plurality of discharge grooves 303 are opened at the top of the blocking block 301. The mixture flows out through the discharge barrel 302 through the discharge grooves 303, and the interior of the discharge grooves 303 is connected with the interior of the discharge barrel 302.

[0032] Example 2

[0033] The self-service coffee machine capsule provided in Example 1 is further optimized, specifically, as Figure 2 and Figure 3 As shown, the blocking member includes a No. 1 blocking ring 401 located outside the blocking block 301, and the No. 1 blocking ring 401 is fixedly connected to the bottom end inside the shell 1. A plurality of discharge ports are opened at the top of the No. 1 blocking ring 401, and the mixture flows into the discharge trough 303 through the discharge ports.

[0034] Further, such as Figure 3 and Figure 4 As shown, the No. 1 mixing element includes a No. 2 blocking ring 402 located outside the No. 1 blocking ring 401. A feed chute is provided at the top of the No. 2 blocking ring 402. The feed chute at the top of the No. 2 blocking ring 402 is inclined. The inclined setting allows the mixture to flow when it passes through the feed chute to between the No. 1 blocking ring 401 and the No. 2 blocking ring 402, thereby being mixed.

[0035] Further, such as Figure 3 and Figure 4As shown, the No. 2 mixing element includes a No. 3 blocking ring 403 located outside the No. 2 blocking ring 402. A number of feed troughs are also provided at the top of the No. 3 blocking ring 403. The feed troughs at the top of the No. 3 blocking ring 403 are tilted. The tilting setting allows the mixture to flow, thereby improving the mixing effect. The feed troughs at the top of the No. 3 blocking ring 403 and the feed troughs at the top of the No. 2 blocking ring 402 have opposite tilt angles. The opposite tilt angles enable the mixture to flow between the No. 3 blocking ring 403 and the No. 2 blocking ring 402 without quickly entering between the No. 1 blocking ring 401 and the No. 2 blocking ring 402, thereby ensuring the flow and mixing time. The No. 3 blocking ring 403 is located inside the ten mounting blocks 501.

[0036] Further, such as Figure 1 and Figure 5 As shown, the two sealing members include two sealing membranes 201 fixed inside the shell 1. The coffee powder is placed between the two sealing membranes 201 to preserve and seal it. The sealing membrane 201 located at the bottom is located above the ten mounting blocks 501. When the extraction device injects liquid, the sealing membrane 201 at the bottom is pushed downward by continuously applying water pressure so that it is punctured by the puncture block 502.

[0037] Example 3

[0038] The self-service coffee machine capsules provided in Example 1 and Example 2 are further optimized, such as Figure 5 As shown, the inner wall of the shell 1 is provided with a plurality of inclined parts. When the liquid is injected through the extraction device, the liquid needs to fill the space between the two sealing membranes 201 with hot water. At this stage, the liquid has already come into contact with the coffee powder and is preliminarily mixed. The inclined parts are used to increase the mixing effect at this stage. The inclined parts are located between the two sealing parts.

[0039] Further, such as Figure 5 As shown, the plurality of inclined parts include a plurality of mixing plates 601 fixed to the inner wall of the shell 1. The mixing plates 601 are arranged at an angle. The inclined mixing plates 601 can use the flow force when the water is just injected to change the flow path of the water flow, so that the water flow forms a more complex flow pattern inside the shell 1, thereby helping the water and coffee powder to be mixed more fully, thereby improving the extraction efficiency and the uniformity of the coffee taste.

[0040] Further, such as Figure 5 As shown, the mixing plate 601 is specifically a spring. The elastic force of the spring can cause the water flow to generate tiny turbulence and eddy currents inside the shell 1. These phenomena help the soluble substances in the coffee powder to dissolve into the water faster and more evenly. At the same time, the design of the spring also helps to reduce the possibility of coffee powder agglomeration and precipitation, further improving the extraction effect.

[0041] The usage process of the self-service coffee machine capsule provided by the utility model is as follows:

[0042] When it is necessary to extract coffee, the extraction device inside the self-service coffee machine uses a piercing tube to puncture the upper sealing film 201 and cover the top of the shell 1, and then inject hot water to fill the inside of the shell 1, and use the mixing plate 601 to increase the mixing effect. After filling, the lower sealing film 201 is squeezed downward by water pressure so that it is punctured by the puncture block 502 below, allowing the mixture to enter the outside of the No. 3 blocking ring 403 through the punctured hole, and enter the No. 3 blocking ring 403 and the No. 2 blocking ring 402 through the material trough to flow and mix, and then enter the No. 2 blocking ring 402 and the No. 1 blocking ring 401 again to flow and mix, and then flow out through the discharge trough 303 and the discharge barrel 302. By placing a container below, the extracted coffee can be caught.
