Description

Technical Field

[0001] The present application belongs to the technical field of extractors, and in particular relates to 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 extraction device is an important component of the capsule-type beverage machine. The extraction device includes a beverage capsule loaded with beverage consumables (such as coffee, milk tea 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] Capsule-type beverage machines have different brewing operations and parameters for different types of beverage capsules. Specifically, the identifier (barcode or QR code) on the beverage capsule is recognized by the identifier, and different brewing parameters are adjusted to perform brewing operations. The identifier is generally installed on the extractor, and the identifier will be affected by various harsh working conditions during the extraction process. Therefore, how to improve the recognition reliability has become a key research and development issue in this field. Utility Model Content

DETAILED DESCRIPTION

[0042] 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.

[0043] 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.

[0044] In the related art, the identifier is generally directly mounted on the extractor, and the identifier will be affected by various adverse working conditions during the extraction process and its recognition reliability will be affected. To this end, the embodiment of the present application provides an extractor 100 and a beverage machine, which can solve the technical problem of low recognition reliability of the current identifier 130 to a certain extent.

[0045] In a first aspect of the present application, an extractor 100 is provided. Figure 1 , Figure 2 and Figure 3 , showing the overall structure diagram and cross-sectional view of the extractor 100. The extractor 100 includes an extractor body 110, a lens 140 and an elastic member 170. The extractor body 110 is provided with a mounting hole 120a, and the lens 140 is arranged in the mounting hole 120a along the mounting hole 120a, and the lens 140 can move along the axial direction of the mounting hole 120a, and the elastic member 170 is also arranged in the mounting hole 120a. Along the moving direction of the lens 140, the elastic member 170 is located between the lens 140 and the extractor body 110. The elastic member 170 can be an elastic material such as rubber, silicone, spring, etc. The elastic member 170 can be an independent component, or it can be a part of the lens 140 or the extractor body 110, and this application does not make any limitation.

[0046] See also Figure 4 and Figure 7The extractor 100 is applied to a capsule-type beverage machine. When the beverage capsule 10 is placed in the beverage machine, the extractor 100 injects fluid into the beverage capsule 10 to extract and brew the beverage consumable in the beverage capsule 10. The beverage machine is also provided with an identifier 130, which is used to identify the identification code on the beverage capsule 10 so that the capsule-type beverage machine adjusts different brewing parameters to perform brewing operations. In order to facilitate the identifier 130 to identify the identification code on the beverage capsule 10, the identifier 130 is installed on the extractor 100 and faces the lens 140. The lens 140 is made of a transparent or translucent material and does not affect the passage of light.

[0047] Since a humid and hot working environment may affect the identifier 130, a lens 140 is arranged in the mounting hole 120a of the extractor body 110. The outer side of the lens 140 is the beverage capsule 10 to be identified, and its working environment is humid and hot, while the inner side of the lens 140 is used to arrange the identifier 130, and its working environment is dry. The humid and hot working environment outside is isolated by the lens 140, and the influence of the humid and hot working environment on the identifier 130 is reduced. At the same time, 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.

[0048] Since the extractor 100 needs to press the beverage capsule 10 during extraction, each time the beverage capsule 10 is loaded, the beverage capsule 10 will collide with the lens 140 of the extractor 100, which will damage the outer surface of the lens 140 in the long term, causing a negative impact on the recognition of the beverage capsule 10. However, the present application arranges the lens 140 in the mounting hole 120a movably along the axial direction of the mounting hole 120a, and at the same time arranges an elastic member 170 in the mounting hole 120a. The elastic member 170 can be a flexible and elastic structural member such as rubber or a spring, so that the elastic member 170 is arranged between the lens 140 and the extractor body 110 along the moving direction of the lens 140. By arranging the flexible and elastic elastic member 170 between the lens 140 and the extractor body 110, when the lens 140 is collided by the beverage capsule 10, the elastic member 170 can play a buffering role, reduce the influence of the beverage capsule 10 on the lens 140, and maintain a better recognition effect.

[0049] The lens 140 can be a flat glass or a convex lens with a magnifying effect. Figure 3In some embodiments, the lens 140 is in a groove shape, and at least the bottom of the groove in the lens 140 is made of a transparent material, so as to facilitate the identifier 130 to identify the beverage capsule 10. By setting the lens 140 in a groove shape, on the one hand, the lens 140 can be stably installed in the mounting hole 120a through the groove wall of the lens 140, the outer peripheral surface of the groove wall of the lens 140 is connected to the hole wall of the mounting hole 120a, and the end of the groove wall of the lens 140 facing the identifier 130 is connected to the elastic member 170; on the other hand, when in use, part of the identifier 130 extends into the groove of the lens 140, and the groove structure plays a certain fixing role for the identifier 130.

[0050] In order to improve the sealing between the lens 140 and the extractor body 110, reduce the fluid or the hot steam generated by the fluid from the gap between the lens 140 and the extractor body 110 to enter the inner side of the lens 140, and affect the identifier 130. Figure 3 In some embodiments, the extractor 100 is provided with a sealing ring 180, so that the sealing ring 180 is arranged between the groove wall of the lens 140 and the hole wall of the mounting hole 120a in a pressurized state, so that the sealing ring 180 seals the gap between the lens 140 and the mounting hole 120a. In order to make the sealing ring 180 have a better sealing effect, an annular groove 140a is provided on the outer surface of the groove wall of the lens 140, so that the sealing ring 180 is located in the annular groove 140a and is pressed against the hole wall of the mounting hole 120a, so that the sealing ring 180 is fixed by the annular groove 140a, thereby improving the sealing effect of the sealing ring 180 between the lens 140 and the mounting hole 120a. In addition, since the hole wall of the mounting hole 120a contacted by the sealing ring 180 is a smooth wall surface, it will not affect the movement of the lens 140.

[0051] See also Figure 3 In some embodiments, the mounting hole 120a is a stepped hole, and the elastic member 170 is axially limited by the shoulder 120b of the mounting hole 120a. The identifier 130 is mounted on the inner side of the lens 140, and the direction in which the lens 140 is hit by the beverage capsule 10 is from the outer side to the inner side of the lens 140. In order to prevent the lens 140 from moving toward the identifier 130 and hitting the identifier 130 after being hit by the beverage capsule 10, the mounting hole 120a is set as a stepped hole, and the elastic member 170 is installed on the shoulder 120b of the mounting hole 120a, and the elastic member 170 is arranged between the groove wall of the lens 140 and the shoulder 120b of the mounting hole 120a. In this way, the elastic member 170 is limited by the shoulder 120b of the mounting hole 120a to prevent the elastic member 170 from displacement.

[0052] In some embodiments, the surface of the lens 140 exposed to the outside is coated with an anti-fog coating, mainly the surface of the area facing the lens of the identifier 130 is coated with an anti-fog coating, for example, the lens 140 is set in a groove shape, and the outer surface of the groove bottom is coated with an anti-fog coating. When the extractor 100 injects fluid into the beverage capsule 10, the fluid or the hot steam generated by the fluid may overflow to the lens 140, thereby affecting the use effect of the lens 140. By applying the anti-fog coating to the surface of the lens 140 exposed to the outside, the influence of the fluid or the hot steam generated by the fluid on the lens 140 is reduced, and the functional effect of the identifier 130 on the identification code on the beverage capsule 10 is ensured. The anti-fog coating can be a known mature anti-fog technical means such as a hydrophilic coating and a hydrophobic coating, and this application does not limit it.

[0053] See also Figure 1 and Figure 2 In some embodiments, the extractor body 110 includes an extractor frame 120, a sealing layer 150 and a puncture needle 160. The extractor frame 120 is provided with a mounting hole 120a. The sealing layer 150 is mounted on one side of the extractor frame 120. The puncture needle 160 is mounted on the extractor frame 120 and penetrates the sealing layer 150, and is used to provide fluid to the water inlet 12a of the beverage capsule 10. The extractor frame 120 provides a mounting base for the lens 140, the sealing layer 150 and the puncture needle 160, so that the lens 140, the sealing layer 150 and the puncture needle 160 are arranged on the extractor body 110 through the extractor frame 120. The mounting hole 120a of the extractor body 110 is arranged on the extractor frame 120, so that the lens 140 is arranged on the extractor frame 120 through the mounting hole 120a. 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 escaping 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.

[0054] In some embodiments, the sealing layer 150 is provided with a first sealing structure 151 protruding outwards. When the extractor 100 presses the beverage capsule 10, the first sealing structure 151 surrounds and presses against the outer periphery of the water inlet hole 12a of the beverage capsule 10. The first sealing structure 151 of the extractor 100 presses and seals the outer periphery of the water inlet hole 12a of the beverage capsule 10, thereby sealing the fluid overflowing from the puncture point or the hot steam generated by the fluid in the first sealing structure 151, and preventing the fluid or the hot steam generated by the fluid from overflowing from the puncture point into the beverage machine.

[0055] See also Figure 3In some embodiments, the first sealing structure 151 is tilted relative to the pressing direction of the extractor 100, so that the first sealing structure 151 can simultaneously apply radial force and axial force to the outer periphery of the water inlet hole 12a of the beverage capsule 10, so that there is sealing pressure between the first sealing structure 151 and the beverage capsule 10 in both radial and axial directions.

[0056] In some embodiments, the extractor frame 120 and / or the sealing layer 150 are provided with a convex second sealing structure 152, which is located at the periphery of the first sealing structure 151 and pressed against the edge of the beverage capsule 10. When the beverage capsule 10 is placed in the 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 extractor 100 on the beverage capsule 10. 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 extractor 100 on the beverage capsule 10. 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 or hot steam generated by the fluid from overflowing from the first sealing structure 151 into the beverage machine.

[0057] See also Figure 1 and Figure 7 In some embodiments, a clearing area 100a is provided on the extractor 100 facing the liquid outlet 14 of the beverage capsule 10, so that the clearing area 100a on the extractor 100 avoids the liquid outlet 14 of the beverage capsule 10, thereby ensuring 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 clearing area 100a, so that the second sealing structure 152 avoids the clearing area 100a while ensuring the sealing effect of the second sealing structure 152 on the area enclosed by it. Since the clearing area 100a is separated between the extractor 100 and the liquid outlet 14 of the beverage capsule 10, the fluid entering the second sealing structure 152 or the condensed liquid of the hot steam generated by the fluid can flow out from the clearing area 100a along the extractor 100 without affecting the liquid discharge of the liquid outlet 14 of the beverage capsule 10.

[0058] The axial direction of the mounting hole 120a should have a projection component parallel to the axial direction of the puncture needle 160. In order for the puncture needle 160 to successfully puncture the beverage capsule 10, it is usually necessary to puncture the beverage capsule 10 perpendicularly. That is, in the relative movement direction, when the beverage capsule 10 is placed in the beverage machine, the beverage capsule 10 moves along the axial direction of the puncture needle 160. Thereby, the elastic member 170 can be deformed in the axial direction of the puncture needle 160, which plays a buffering effect.

[0059] In some embodiments, the axial direction of the mounting hole 120a is parallel to the axial direction of the puncture needle 160, so that the beverage capsule 10 can collide with the lens 140 along the axial direction of the mounting hole 120a. Since the lens 140 is movably disposed in the mounting hole 120a along the axial direction of the mounting hole 120a, and the elastic member 170 is disposed in the mounting hole 120a and along the moving direction of the lens 140, the elastic member 170 is located between the lens 140 and the extractor body 110, so that the elastic member 170 can play a better buffering effect.

[0060] The second aspect of the present application provides a beverage machine, which includes the extractor 100 of any embodiment of the first aspect. The beverage machine can be a capsule coffee machine, a milk tea machine, a tea maker, etc., and the present application does not limit it.

[0061] See also Figure 4 In some embodiments, the beverage machine includes a device body and a brewing unit installed in the device body, the brewing unit includes a capsule holder 200, a beverage capsule 10, an identifier 130 and an extractor 100 of any embodiment of the first aspect described above, the capsule holder 200 is provided with a capsule cavity 210, the beverage capsule 10 is arranged in the capsule cavity 210, the extractor 100 is installed in the capsule holder 200, and the identifier 130 is installed in the extractor 100 and faces the lens 140.

[0062] See also Figure 5 , 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.

[0063] See also Figure 5 and Figure 6The 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.

[0064] See also Figure 5 and Figure 6 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 first sealing structure 151 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 7 After 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 arranged around the outer circumference of the water inlet hole 12a, and the annular weakened structure 12b is arranged corresponding to the first sealing structure 151 of the extractor 100, so that 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 hole 12a of the upper filter plate 12 and the annular weakened structure 12b.

[0065] When the extractor 100 is pressed against the beverage capsule 10, 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 the annular weakened structure 12b can be flexibly deformed, and the upper filter disc 12 also applies a reaction pressure to the first sealing structure 151 of the extractor 100, so that the first sealing structure 151 of the extractor 100 is elastically deformed. In this way, the first sealing structure 151 of the extractor 100 and the annular weakened structure 12b are used to cooperate with each other, so that the first sealing structure 151 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 first sealing structure 151 of the extractor 100, so as to prevent the fluid or the hot steam generated by the fluid 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.

[0066] See also Figure 6 In 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.

[0067] In some embodiments, the first sealing structure 151 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 first sealing structure 151 of the extractor 100 surrounds and presses against the opening of the cavity 12c. The cavity wall of the cavity 12c surrounds the first sealing structure 151 of the extractor 100, which can prevent the first sealing structure 151 of the extractor 100 from sliding out of the cavity 12c, thereby ensuring the sealing effect.

[0068] 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 6 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.

[0069] 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.

[0070] 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 6In 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 cavity 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 cavity 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 first sealing structure 151 of the extractor 100 surrounds and presses against the cavity opening of the concave cavity 12c, the sealing film 13 is pressed between the first sealing structure 151 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.

[0071] 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.

[0074] 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.
