Description

Technical Field

[0001] The present application belongs to the technical field of brewing units, and in particular relates to a beverage capsule, an extractor and a beverage machine. Background Art

[0002] At present, capsule-type beverage machines are becoming more and more popular due to their simple operation, safety, hygiene and guaranteed beverage quality. The brewing unit is an important component of the capsule-type beverage machine. The brewing unit includes a beverage capsule loaded with beverage consumables (such as coffee, milk tea, cocoa powder or tea leaves, etc.) and an extractor for injecting fluid (such as boiling water, steam, hot milk, etc.) into the beverage capsule. The beverage capsule is placed in the beverage machine, and then the fluid (such as boiling water, steam, hot milk, etc.) is injected into the beverage capsule to extract the beverage consumables. Finally, the brewed beverage flows out of the beverage machine for the user to enjoy.

[0003] Since the fluid injected into the beverage capsule by the extractor is usually a high-temperature fluid with a certain flow rate, in order to prevent the fluid or the hot steam generated by the fluid from overflowing from the capsule puncture point into the beverage machine, it is usually necessary to set a sealing structure on the extractor. According to the mature capsule extraction scheme in the industry, the sealing position between the extractor and the beverage capsule is generally set at the outermost edge of the beverage capsule. The existing sealing scheme will still cause steam overflow after long-term use, resulting in condensed water at the brewing unit, affecting the user experience. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0038] In the related art, in order to withstand the maximum liquid reverse pressure during brewing, the sealing position of the extractor and the beverage capsule is generally set at the outermost edge of the beverage capsule. The existing sealing solution will still cause steam overflow after long-term use, resulting in condensation water at the brewing unit, affecting the user experience.

[0039] The embodiment of the present application provides a beverage capsule 10, an extractor 100 and a beverage machine, which can solve the technical problem of poor sealing effect of the current brewing unit to a certain extent.

[0040] In a first aspect of the present application, a beverage capsule is provided. When the beverage capsule is used in a beverage machine, it needs to cooperate with an extractor, through which the extractor pierces the surface sealing film and injects a fluid medium into the cup. The content of the beverage capsule is not limited to coffee, milk tea powder, scented tea, cocoa powder or tea leaves.

[0041] See also Figure 1 , shows a cross-sectional view of a beverage capsule in one or more embodiments. The beverage capsule 10 comprises a cup body 11, an upper filter disc 12 and a sealing film 13 connected in sequence. The upper filter disc 12 covers the mouth of the cup body 11 to form a closed brewing chamber 11a. The beverage consumable A is filled in the brewing chamber 11a and brewed in the brewing chamber 11a. The upper filter disc 12 can be a disc structure with an edge, completely covering the mouth of the cup body 11; the upper filter disc 12 can also be a circular plate structure, embedded in the mouth of the cup body 11.

[0042] See also Figure 1 and Figure 2 The upper filter plate 12 is provided with a water inlet 12a, which is connected to the brewing chamber 11a, so that the fluid can be injected into the brewing chamber 11a through the water inlet 12a. The sealing film 13 is connected to the upper filter plate 12 and is used to cover the water inlet 12a to prevent the water inlet 12a from being contaminated, thereby affecting the brewing quality of the beverage consumable.

[0043] See also Figure 1 and Figure 2 The upper filter plate 12 is provided with an annular weakening structure 12b at a position surrounding the outer periphery of the water inlet hole 12a. When the extractor 100 is pressed against the beverage capsule 10, the sealing structure of the extractor 100 surrounds and presses against the area between the water inlet hole 12a of the upper filter plate 12 and the annular weakening structure 12b. The beverage capsule 10 is applied to a beverage machine having the extractor 100. Figure 8After the beverage capsule 10 is placed into the beverage machine, the extractor 100 is pressed against the beverage capsule 10. At the same time, the water inlet 12a is arranged corresponding to the puncture needle 160 of the extractor 100, and the puncture needle 160 punctures the sealing film 13 to inject fluid into the water inlet 12a through the puncture needle 160. Since the fluid injected into the beverage capsule 10 by the extractor 100 is usually a high-temperature fluid with a certain flow rate, such as hot water, hot milk, hot steam, etc., in order to prevent the fluid or the hot steam generated by the fluid from overflowing from the puncture point of the beverage capsule 10 into the beverage machine, an annular weakening structure 12b for sealing is provided on the upper filter disc 12. The annular weakened structure 12b is disposed around the outer periphery of the water inlet hole 12a, and the annular weakened structure 12b is disposed correspondingly to the sealing structure of the extractor 100, so that when the extractor 100 is pressed against the beverage capsule 10, the sealing structure of the extractor 100 surrounds and presses against the area between the water inlet hole 12a of the upper filter plate 12 and the annular weakened structure 12b.

[0044] When the extractor 100 is pressed against the beverage capsule 10, the sealing structure of the extractor 100 applies pressure to the portion of the upper filter disc 12 located in the annular weakened structure 12b, and the annular weakened structure 12b can be flexibly deformed, and the upper filter disc 12 also applies a reaction pressure to the sealing structure of the extractor 100, so that the sealing structure of the extractor 100 is elastically deformed. In this way, the sealing structure of the extractor 100 and the annular weakened structure 12b are used to cooperate with each other, so that the sealing structure of the extractor 100 and the annular weakened structure 12b are sealed together. Thus, the fluid overflowing from the puncture point or the hot steam generated by the fluid is sealed in the area sealed by the sealing structure of the extractor 100, and the fluid or the hot steam generated by the fluid is prevented from overflowing from the puncture point into the beverage machine. In addition, by setting the sealing position between the beverage capsule 10 and the extractor 100 between the water inlet hole 12a of the upper filter plate 12 and the annular weakened structure 12b, compared with the prior art in which the sealing position between the beverage capsule 10 and the extractor 100 is set at the outermost edge of the beverage capsule 10, the setting method of the sealing position between the beverage capsule 10 and the extractor 100 of the present application can reduce the area of ​​the sealing region, thereby improving the sealing effect compared with the prior art.

[0045] See also Figure 2In some embodiments, the center of the upper filter disc 12 is concave to form a concave cavity 12c, and the water inlet 12a is provided on the wall of the concave cavity 12c. When the beverage capsule 10 is placed in the beverage machine, the needle 160 of the extractor 100 punctures the sealing film 13 to inject fluid into the water inlet 12a. Since the fluid has a high flow rate, the high-speed fluid directly acts on the water inlet 12a, which will cause the fluid to be unable to stably enter the brewing chamber 11a, thereby affecting the extraction effect of the fluid on the beverage consumable. In order to better inject the fluid discharged by the needle 160 into the water inlet 12a, a concave cavity 12c is provided on the upper filter disc 12 to serve as a transition cavity and a pressure cavity. Most of the high-speed fluid discharged by the needle 160 will not directly act on the water inlet 12a, but will first fill the entire concave cavity 12c, and then be discharged into the water inlet 12a provided on the wall of the concave cavity 12c, so as to transition the fluid through the concave cavity 12c and prevent the high-speed fluid from directly acting on the water inlet 12a. The high-speed fluid continuously discharged from the needle 160 applies pressure to the cavity 12c, so that the fluid in the cavity 12c is stably discharged from the water inlet 12a under the action of pressure, and the fluid is prevented from flowing back from the brewing cavity 11a. The fluid stably injected into the brewing cavity 11a can better extract the beverage consumable, thereby improving the brewing effect.

[0046] In some embodiments, the sealing structure of the extractor 100 surrounds and presses against the opening of the cavity 12c. By pressing the extractor 100 against the beverage capsule 10, the sealing structure of the extractor 100 surrounds and presses against the opening of the cavity 12c. The cavity wall of the cavity 12c surrounds the sealing structure of the extractor 100, which can prevent the sealing structure of the extractor 100 from sliding out of the cavity 12c, thereby ensuring the sealing effect.

[0047] In order to improve the uniformity of the fluid injected into the brewing chamber 11a from the water inlet hole 12a, please refer to Figure 2 In some embodiments, a plurality of water inlet holes 12a are provided, and the plurality of water inlet holes 12a are distributed around the wall of the concave cavity 12c. The fluid can enter the brewing cavity 11a more evenly through the plurality of water inlet holes 12a, thereby further improving the extraction brewing effect. While ensuring the uniformity of the fluid injected into the brewing cavity 11a from the water inlet holes 12a, in order to ensure that the fluid can be stably injected into the brewing cavity 11a from the water inlet holes 12a, the area of ​​the water inlet holes 12a is set to 0.03mm 2 ~1mm 2 A too small water inlet hole 12a will affect the efficiency of the fluid discharge from the water inlet hole 12a, while a too large water inlet hole 12a will result in insufficient pressure in the cavity 12c to act on the fluid, thereby reducing the extraction effect of the fluid on the beverage consumable. The area of ​​the water inlet hole 12a can be 0.03mm 2 , 0.4mm 2 , 0.5mm 2, 0.6mm 2 , 0.7mm 2 , 0.8mm 2 , 0.9mm 2 , 0.95mm 2 Etc., this application is not limited.

[0048] In some embodiments, a plurality of water inlet holes 12a are distributed around the circumference of the cavity 12c. Since the needle 160 of the extractor 100 is usually facing the bottom of the cavity 12c, the water inlet holes 12a are arranged on the circumference of the cavity 12c to prevent the high-speed fluid discharged by the needle 160 from directly acting on the water inlet holes 12a, so as to improve the transition effect and pressure effect of the cavity 12c on the fluid. The shape, size and number of the water inlet holes 12a can be determined according to actual conditions, and are not limited in this application. In some embodiments, the water inlet holes 12a are arranged as circular holes with an inner diameter of 0.2 mm to 1 mm.

[0049] The sealing film 13 is fixedly connected to the cup body 11 and / or the upper filter disc 12 to seal the brewing chamber 11a. Figure 2 In some embodiments, the surface of the upper filter disc 12 facing the sealing film 13 (hereinafter referred to as the first surface) is provided with an annular surface 12d, and the annular surface 12d is located between the annular weakening structure 12b and the opening of the concave cavity 12c. The sealing film 13 is fixedly connected to the annular surface 12d, for example, the sealing film 13 and the annular surface 12d are hot-pressed and fused. The sealing film 13 is used to cover the water inlet 12a. By setting the annular surface 12d between the annular weakening structure 12b and the opening of the concave cavity 12c, the sealing film 13 is fixedly connected to the annular surface 12d, so that the sealing film 13 covers the water inlet 12a. In addition, since the sealing structure of the extractor 100 surrounds and presses against the opening of the concave cavity 12c, the sealing film 13 is pressed between the sealing structure of the extractor 100 and the upper filter disc 12, so that the puncture needle 160 of the extractor 100 can better puncture the sealing film 13.

[0050] In some embodiments, other annular surfaces or annular protrusions may be provided on the first surface of the upper filter disc 12, and these annular surfaces or annular protrusions are all located at the periphery of the annular surface 12d, and the sealing film 13 is hot-pressed and fused with these annular surfaces or annular protrusions. The sealing film 13 usually needs to display relevant information of the capsule, such as the type of contents, the content, the brewing method, etc. In order to ensure that the sealing film 13 has enough area for information display, the sealing film 13 should be hot-pressed and fused to the end surface of the entire beverage capsule 10.

[0051] See also Figure 1In some embodiments, the cup body 11 includes an inner cup 11d and an outer cup 11e, the outer cup 11e is sleeved outside the inner cup 11d, a fluid channel 11b is formed between the inner cup 11d and the outer cup 11e, and the inner cup 11d is provided with a lower filter disc 11c, and the lower filter disc 11c connects the brewing chamber 11a and the fluid channel 11b. Under this structural setting condition, the upper filter disc 12 and the inner cup 11d are surrounded to form a closed brewing chamber 11a, and the beverage consumable is brewed in the brewing chamber 11a of the inner cup 11d. The fluid is injected into the brewing chamber 11a of the inner cup 11d through the water inlet 12a of the upper filter disc 12, and the fluid extracts the beverage consumable in the brewing chamber 11a. The extract passes through the lower filter disc 11c provided on the inner cup 11d and flows from the brewing chamber 11a into the fluid channel 11b between the inner cup 11d and the outer cup 11e. The lower filter plate 11c can be arranged at the bottom of the inner cup 11d, or at the wall of the inner cup 11d, or at both the bottom and the wall of the cup, which is not limited in the present embodiment. In some embodiments, the cup body 11 can also be an integrated structure with a hollow wall, and a filter device is arranged in the cavity of the cup wall.

[0052] See also Figure 1 In some embodiments, the surface of the upper filter disc 12 facing the cup bottom (hereinafter referred to as the second surface) is provided with an annular convex edge 12e, the annular convex edge 12e extends into the inner cup 11d and is in close contact with the cup wall of the inner cup 11d, and the annular convex edge 12e and / or the edge 12f of the upper filter disc 12 are fixedly connected to the inner cup 11d. That is, the inner cup 11d can be a cup body with an upper opening, the annular convex edge 12e extends into the inner cup 11d and is in close contact with the cup wall of the inner cup 11d, and the two are fixed by welding or hot melting; the inner cup 11d can also be a cup body with a flange, the annular convex edge 12e extends into the inner cup 11d and is in close contact with the cup wall of the inner cup 11d, and the edge 12f of the upper filter disc 12 is also in close contact with the flange of the inner cup 11d, and the upper filter disc 12 is fixed to the inner cup 11d by welding or hot melting.

[0053] By providing an annular convex edge 12e on the second surface opposite to the first surface of the upper filter disc 12, the annular convex edge 12e on the upper filter disc 12 is used as a positioning structure to position the upper filter disc 12 on the inner cup 11d. In addition, in order to fix the upper filter disc 12 and the inner cup 11d together, the annular convex edge 12e can be fixedly connected to the inner cup 11d, or the edge of the upper filter disc 12 can be fixedly connected to the inner cup 11d, or the annular convex edge 12e, the edge of the upper filter disc 12 and the inner cup 11d can be fixedly connected at the same time, and the embodiment of the present application does not limit this.

[0054] In a second aspect of the present application, an extractor is provided, which is adapted to the beverage capsule of any one of the first aspects. When the beverage capsule of any one of the first aspects is loaded into the beverage machine, the beverage capsule is compressed by the extractor. Figure 3 , Figure 4 and Figure 6 , showing a schematic diagram and a full cross-sectional view of the structure of the extractor in different embodiments of the present application. The extractor 100 is provided with a first convex sealing structure 151, the first sealing structure 151 is made of elastic material, and the position of the first sealing structure 151 in the extractor 100 is set as follows: when the extractor 100 is pressed against the beverage capsule 10, the first sealing structure 151 of the extractor 100 surrounds and presses against the area between the water inlet 12a of the upper filter plate 12 and the annular weakening structure 12b.

[0055] The first sealing structure 151 of the extractor 100 applies pressure to the portion of the upper filter disc 12 located in the annular weakened structure 12b, and at the same time, the portion of the upper filter disc 12 located in the annular weakened structure 12b will apply a reaction pressure to the first sealing structure 151 under the action of the annular weakened structure 12b. In this way, the first sealing structure 151 and the annular weakened structure 12b are used in cooperation, so that the first sealing structure 151 and the annular weakened structure 12b are sealed together. Thus, the fluid overflowing from the puncture point or the hot steam generated by the fluid is sealed in the first sealing structure 151, and the fluid or the hot steam generated by the fluid is prevented from overflowing from the puncture point into the beverage machine. In addition, by setting the sealing position between the extractor 100 and the beverage capsule 10 between the water inlet hole 12a of the upper filter plate 12 and the annular weakening structure 12b, compared with the prior art in which the sealing position between the extractor 100 and the beverage capsule 10 is set at the outermost edge of the beverage capsule 10, the setting method of the sealing position between the extractor 100 and the beverage capsule 10 in the embodiment of the present application can reduce the area of ​​the sealing region, thereby improving the sealing effect compared with the prior art.

[0056] In order to further improve the sealing effect of the first sealing structure 151 on the upper filter disc 12, in some embodiments, the first sealing structure 151 is inclined relative to the upper filter disc 12 in both the radial and axial directions, so that the first sealing structure 151 can apply radial pressure and axial pressure to the upper filter disc 12 at the same time, thereby ensuring that there is sealing pressure between the first sealing structure 151 and the upper filter disc 12 in both the radial and axial directions.

[0057] In some embodiments, the center of the upper filter disc 12 is concave to form a cavity 12c, the water inlet 12a is provided on the cavity wall of the cavity 12c, and the first sealing structure 151 of the extractor 100 surrounds and presses against the cavity opening of the cavity 12c. Thus, the first sealing structure 151 can press against the cavity opening of the cavity 12c in a manner of being inclined relative to the radial and axial directions of the upper filter disc 12, and by applying radial force and axial force to the cavity opening of the cavity 12c, there is sealing pressure between the first sealing structure 151 and the upper filter disc 12 in both the radial and axial directions, thereby further improving the sealing effect of the first sealing structure 151 on the upper filter disc 12.

[0058] In some embodiments, the extractor 100 is further provided with a convex second sealing structure 152, and the second sealing structure 152 is pressed against the edge of the beverage capsule 10. When the beverage capsule 10 is placed in a capsule-type beverage machine, the extractor 100 will be pressed against the beverage capsule 10 to fix the beverage capsule 10 in the beverage machine, so that the extractor 100 extracts the beverage capsule 10. In the prior art, the extractor 100 presses and seals the outermost edge of the beverage capsule 10, so as to achieve the sealing effect of the extractor 100 on the beverage capsule 10 and to achieve the fixation of the beverage capsule 10 by the extractor 100. In the embodiment of the present application, the first sealing structure 151 is used to seal the beverage capsule 10. In order to fix the extractor 100, the second sealing structure 152 is provided, so that the second sealing structure 152 is pressed against the edge of the beverage capsule 10 to achieve the fixation of the beverage capsule 10 by the extractor 100. In addition, since the second sealing structure 152 is pressed against the edge of the beverage capsule 10 , the second sealing structure 152 also has a sealing effect on the beverage capsule 10 to prevent the fluid overflowing from the first sealing structure 151 or the hot steam generated by the fluid from overflowing into the beverage machine.

[0059] In the capsule-type beverage machine, the beverage capsule 10 has two placement postures: horizontal and vertical. Among them, the beverage consumables in the horizontal beverage capsule 10 are in contact with the fluid medium for a longer time than the beverage consumables in the vertical beverage capsule 10 (when placed vertically, the fluid is easy to flow out under its own weight, making the contact time shorter), thereby having a better extraction and brewing effect.

[0060] See also Figure 7 and Figure 8In some embodiments, the beverage capsule 10 is compressed by the extractor 100 in a horizontal posture, and the liquid outlet 14 of the beverage capsule 10 is located at the cup mouth of the cup body 11, so as to be suitable for a beverage machine in which the beverage capsule 10 is placed horizontally. Correspondingly, a clearance zone 110 is provided on the extractor 100 directly opposite to the liquid outlet 14 of the beverage capsule 10. In this way, the liquid outlet 14 of the beverage capsule 10 is avoided by the clearance zone 110 on the extractor 100, so as to ensure the liquid discharge effect of the liquid outlet 14 of the beverage capsule 10. In addition, the second sealing structure 152 of the extractor 100 is in an arc shape, and both ends of the arc-shaped second sealing structure 152 are located at the edge of the clearance zone 110, so as to ensure the sealing effect of the second sealing structure 152 on the area enclosed by it, and at the same time, the second sealing structure 152 avoids the clearance zone 110. Since there is a clearing area 110 between the extractor 100 and the liquid outlet 14 of the beverage capsule 10 , the fluid entering the second sealing structure 152 or the condensate of the hot steam generated by the fluid can flow out from the clearing area 110 along the extractor 100 without affecting the liquid outflow from the liquid outlet 14 of the beverage capsule 10 .

[0061] In some embodiments, the cup body 11 includes an inner cup 11d and an outer cup 11e, the outer cup 11e is sleeved outside the inner cup 11d, a fluid channel 11b is formed between the inner cup 11d and the outer cup 11e, and the inner cup 11d is provided with a lower filter disc 11c, the lower filter disc 11c connects the brewing chamber 11a and the fluid channel 11b. The fluid is injected into the brewing chamber 11a of the inner cup 11d through the water inlet 12a of the upper filter disc 12, the fluid extracts the beverage consumable in the brewing chamber 11a, the extract passes through the lower filter disc 11c provided on the inner cup 11d, flows from the brewing chamber 11a into the fluid channel 11b between the inner cup 11d and the outer cup 11e, and finally the extract flows out from the outlet of the fluid channel 11b, the outlet of the fluid channel 11b is the liquid outlet 14 of the beverage capsule 10.

[0062] The capsule-type beverage machine has different brewing operations and parameters for brewing different types of beverage capsules 10. Specifically, the identifier 130 recognizes the identification code (barcode or QR code) on the beverage capsule 10, thereby adjusting different brewing parameters for brewing operations. In order to facilitate the identifier 130 to recognize the identification code on the beverage capsule 10, the identifier 130 is usually installed on the extractor 100.

[0063] See also Figure 4 and Figure 5In some embodiments, the extractor 100 includes an extractor frame 120 and a sealing layer 150. The extractor frame 120 is provided with a lens 140. The lens 140 is located outside the area surrounded by the first sealing structure 151. The sealing layer 150 is arranged on the side of the extractor frame 120 facing the beverage capsule 10 and avoids the lens 140 to avoid covering the lens 140. The lens 140 is made of a transparent or translucent material for alignment with the identifier 130. In some embodiments, the surface of the lens 140 is coated with an anti-fog coating to reduce the impact of the fluid or the hot steam generated by the fluid on the lens 140 through the anti-fog coating, so as to ensure the functional effect of the identifier 130 on the identification code on the beverage capsule 10. The anti-fog coating can be a known mature anti-fog technology such as a hydrophilic coating and a hydrophobic coating, which is not limited in this application.

[0064] See also Figure 3 and Figure 6 The extractor 100 further includes a puncture needle 160, which is mounted on the extractor frame 120 and penetrates the sealing layer 150, and the puncture needle 160 is arranged in the first sealing structure 151. The puncture needle 160 is used to puncture the capsule beverage, so that after the puncture needle 160 punctures the inside of the capsule beverage, the fluid is injected into the capsule beverage. The sealing layer 150 is mainly used to seal the area of ​​the capsule beverage punctured by the puncture needle 160 to prevent the fluid or the hot steam generated by the fluid from overflowing from the puncture point of the beverage capsule 10 into the beverage machine. Therefore, the sealing layer 150 is installed on the side of the extractor frame 120 facing the capsule beverage, and the puncture needle 160 is installed on the extractor frame 120 and penetrates the sealing layer 150. And by arranging the puncture needle 160 in the first sealing structure 151, the sealing setting of the first sealing structure 151 on the puncture point is realized.

[0065] The extractor frame 120 provides a mounting base for the identifier 130, the lens 140 and the sealing layer 150, so that the identifier 130, the lens 140 and the sealing layer 150 can be arranged in the extractor 100 through the extractor frame 120, and the sealing layer 150 provides a mounting base for the first sealing structure 151. The identifier 130 installed on the extractor 100 is usually used to identify the beverage capsule 10 that has been placed in the beverage machine and compressed by the extractor 100. In other words, the identifier 130 needs to be arranged on the extractor frame 120 in a direction facing the beverage capsule 10. The sealing layer 150 is also arranged on the extractor frame 120 in a direction facing the beverage capsule 10 because it is provided with the first sealing structure 151 for sealing the beverage capsule 10. Therefore, the sealing layer 150 needs to avoid the identifier 130.

[0066] In addition, since the humid and high temperature working environment may affect the identifier 130, a lens 140 is provided on the extractor frame 120, and the identifier 130 is installed in the extractor frame 120 and faces the lens 140. Correspondingly, the sealing layer 150 avoids the lens 140. The humid and high temperature working environment outside the lens 140 is isolated to reduce the influence of the humid and high temperature working environment on the identifier 130, and the identifier 130 can recognize the identification code on the beverage capsule 10 through the lens 140 without directly contacting the beverage capsule 10, thereby improving the recognition reliability of the identifier 130.

[0067] See also Figure 5 In some embodiments, the sealing layer 150 is attached to a partial area of ​​the side of the extractor frame 120 facing the beverage capsule 10, and the area not attached by the sealing layer 150 forms the lens 140. The sealing layer 150 is arranged on the side of the extractor frame 120 facing the beverage capsule 10 by an attachment method, so as to realize the arrangement of the sealing layer 150 on the side of the extractor frame 120 facing the beverage capsule 10. In addition, the sealing layer 150 is only attached to a partial area of ​​the side of the extractor frame 120, and the area on the extractor frame 120 not attached by the sealing layer 150 forms the lens 140. In this way, the lens 140 is integrated with the extractor frame 120, so that the lens 140 and the extractor frame 120 are an integrated structure, thereby preventing the fluid or the hot steam generated by the fluid from entering the inner side of the lens 140 from the gap between the lens 140 and the extractor frame 120, and affecting the identifier 130. In order to enable the area of ​​the extractor frame 120 to which the sealing layer 150 is not attached to form the lens 140, the extractor frame 120 can be set to high-temperature resistant food-grade transparent glass, transparent plastic, etc.

[0068] The sealing layer 150 may also be a sealing member installed at the position of the needle 160 of the extractor frame 120, and the needle 160 penetrates the sealing layer 150, such as Figure 6 In some embodiments, the lens 140 and the extractor frame 120 may also be configured as a split structure, and the material of the extractor frame 120 is not limited to a transparent material, and may be a conventional plastic.

[0069] The first sealing structure 151 surrounds the needle 160. The first sealing structure 151 is disposed on the sealing layer 150 and is made of an elastic and deformable material. The second sealing structure 152 can be disposed on the sealing layer 150 or the extractor frame 120. Figure 5 The second sealing structure 152 is also disposed on the sealing layer 150. The second sealing structure 152 is also made of an elastic and deformable material, and can improve the sealing effect by pressing the beverage capsule 10. Figure 6The second sealing structure 152 is a protrusion provided on the extractor frame 120 . The extractor frame 120 is made of PPA plastic and presses the beverage capsule 10 .

Figure 7 and Figure 8 In some embodiments, the brewing unit includes a capsule holder 200, a beverage capsule 10, and an extractor 100. The capsule holder 200 is provided with a capsule cavity 210, the beverage capsule 10 is disposed in the capsule cavity 210, and the extractor 100 is mounted on the capsule holder 200. When the beverage capsule 10 is placed in the beverage machine, the beverage capsule 10 is mounted on the capsule holder 200, and the capsule holder 200 drives the extractor 100 to move, so as to press the extractor 100 against the beverage capsule 10.

[0072] See also Figure 8 After the beverage capsule 10 is placed into the beverage machine, the extractor 100 is pressed against the beverage capsule 10, and the first sealing structure 151 of the extractor 100 is pressed against the beverage capsule 10, and the pressing position is aligned with the area between the water inlet hole 12a of the upper filter plate 12 and the annular weakening structure 12b. In addition, since the extractor 100 is pressed against the beverage capsule 10, the cup body 11 and the upper filter plate 12 of the beverage capsule 10 are deformed to a certain extent, and a liquid outlet 14 is formed on the cup body 11. At the same time, the puncture needle 160 of the extractor 100 pierces the sealing film 13 of the beverage capsule 10 and provides the fluid medium C to the water inlet hole 12a of the beverage capsule 10. The fluid medium C enters the brewing chamber 11a through the water inlet hole 12a to extract the beverage consumable A to obtain the beverage B, and the beverage B is discharged from the beverage capsule 10 through the liquid outlet 14 of the beverage capsule 10.
