Description

Technical Field

[0001] The present invention relates to the technical field of beverage extraction devices, and in particular to a release package and a beverage extraction device having the release package. The extraction device may be a capsule coffee machine or other similar equipment. Background Art

[0002] The beverage extraction device can extract beverage packages similar to jelly packages that are packaged with coffee powder. When in use, the beverage package is placed in the extraction device, and the two parts in the extraction device are closed by a driving mechanism to form a closed extraction chamber, and high-pressure hot water is injected into the beverage package for extraction. After the extraction is completed, the used beverage package needs to be taken out to prepare for the next extraction. For ease of operation, the existing beverage extraction device can already realize automatic package removal. After the two parts are opened to each other, the beverage package can automatically fall into the material storage box inside the extraction device. There is no need to take the beverage package out of the chamber by hand and discard it every time. Instead, it only needs to be taken out and dumped after multiple uses. This operation is more convenient and user-friendly.

[0003] The automatic package-removing mechanism in the existing beverage extraction device, such as the Chinese invention patent "Automatic Package-Removing Mechanism of Beverage Preparation Device" with announcement number CN102670076B, is respectively provided with two clamping plates on the left and right sides of the second machine part in order to realize the automatic package-removing function. At the same time, two sets of guide grooves for guiding the front and rear axes of the clamping plates are provided on the machine base. The front end of the clamping plate has a blocking portion. Under the guiding cooperation of the guide groove and the front axis, the front end of the clamping plate can be opened and closed relative to the second machine part. When the two machines are fully opened, the two clamping plates are closed to clamp the beverage package; during the forward movement of the second machine part, the two clamping plates are opened to make way for the beverage package to pass smoothly; when the two machines are fully closed, the blocking portion is located in the notch of the first machine part; when the second machine part is moved backward, the blocking portion contacts the annular edge of the beverage package with the backward movement of the second machine part to drive the beverage package to fall, and the push of the blocking portion can smoothly push the beverage package out of the accommodating cavity of the first machine part to ensure the reliability of package-removing. The package-switching mechanism involves many parts, and the relative positional relationships and assembly relationships are complex, and the assembly precision requirements are high, and the assembly is not convenient.

[0004] Further improvements have been made, such as the Chinese invention patent with announcement number CN104433814A "Beverage Brewing Device that Facilitates the Removal of Beverage Packets", in which the beverage packets are removed by a packet scraper plate. The packet scraper plate is arranged on the upper part of the first mechanism and can move up and down. The components involved include the packet scraper plate, two springs and a pressure plate. The structure is still not streamlined enough. In addition, the spring needs to act on the packet scraper plate to keep the packet scraper plate moving downward, which has high requirements for assembly.

[0005] Another example is the Chinese invention patent "Package-removing plate and beverage brewing device with the same" with publication number CN107184102A. The pack removal can be completed by simply installing the pack removal plate directly on the beverage brewing device. It does not need to cooperate with other elastic components during assembly. The number of components involved is small and the structure is simple. However, the structure of the pack removal plate itself is still relatively complex. In order to ensure that the arm itself has good elasticity, perforations and notches are provided. The rear of the base is also provided with a mounting plate extending backwards. The structure has high requirements for the manufacturing accuracy of the components. In addition, in order to realize the pack release function, the pack removal plate also needs to be provided with a holding structure for receiving and holding the beverage pack between the two components near the first component in the base. In view of this, it is necessary to make further improvements. Summary of the invention

[0006] A technical problem to be solved by the present invention is to provide a packaging release component with simple structure, convenient assembly and low cost in view of the above-mentioned existing technical status, and can effectively realize the placement and automatic release of beverage packages.

[0007] Another technical problem to be solved by the present invention is to provide a beverage extraction device having the above-mentioned release package in view of the above-mentioned existing technical status.

[0008] The technical solution adopted by the present invention to solve the above technical problems is as follows: the release package of the present invention comprises a base for being fixedly mounted on the beverage extraction device, a blocking portion formed by bending and extending toward each other in the machine base at both ends of the base, and an arm portion for placing the annular edge of the beverage package formed by bending and extending backward at the end of the blocking portion; the blocking portion and the arm portion are elastic, and the distance between the two arms in a free state is smaller than the outer diameter of the annular edge of the beverage package and larger than the outer diameter of the beverage package body; when the beverage package is pushed forward, The retaining portion and the arm portion can be expanded outward under the squeezing action of the annular edge, so that the annular edge of the beverage package can move forward from between the two arms and pass over the retaining portion; when the retaining portion and the arm portion are in a free state, the outer diameter of the annular edge of the beverage package is larger than the distance between the two inner ends of the retaining portion and smaller than the distance between the two outer ends of the retaining portion, and after passing over the retaining portion, the annular edge of the beverage package will automatically retract and reset inward under the action of the elastic force of the retaining portion and the two arms, so that the annular edge of the beverage package can be blocked by the retaining portion and cannot move backward.

[0009] The release package of the present invention can be a split component, that is, the aforementioned base includes two independent components, one end of each component is used for fixed installation on the beverage extraction device, and the other end is bent and extended to form the blocking part, i.e., the arm part, etc. In this case, those skilled in the art should understand that the part of the two components used for fixed installation together constitutes the aforementioned base. Of course, the release package is preferably an integrated structure, because the product with an integrated structure will be more conducive to production and easier to install.

[0010] Preferably, the release package of the present invention is formed by bending a spring steel wire. The spring steel wire itself has elasticity, which is conducive to the outward expansion and reset of the arm, and is also conducive to the installation of the base outside the machine base. It has a simple structure, is easy to process and manufacture, and has a low cost. Of course, the release package can also be made of other materials that are both elastic and rigid.

[0011] Preferably, the end of the arm portion is extended with a guide portion that gradually expands outward. During the forward movement of the beverage package, the piston cavity will cover the beverage package and push it forward. The outward-expanding guide portion is used to expand the distance between the rear ends of the two arms and guide the piston to smoothly enter between the two arms, so as to effectively prevent the piston from failing to accurately fit between the two arms due to inaccurate positioning during the forward movement of the driving mechanism, thereby avoiding obstacles to the forward travel of the piston. Although, if there is no guide portion, the desired function can be achieved as long as the size is accurately matched, but it will increase the difficulty of production and manufacturing.

[0012] The beverage extraction device of the present invention comprises

[0013] A machine base with a bag loading opening and a bag switching opening;

[0014] A first part and a second part are respectively restrained at the front and rear of the base, wherein the second part can move forward and backward relative to the first part to close or open relative to the first part;

[0015] Features:

[0016] The second mechanism has a cavity for accommodating a beverage package with an annular edge; and the first mechanism is equipped with a release package as described above;

[0017] The base of the release package is fixed relative to the first mechanism, a gap is provided between the stopper portion of the release package and the rear end surface of the first mechanism for placing the annular edge of the beverage package, and a clamping opening is formed between the two arms for placing the annular edge of the beverage package;

[0018] When placing the package, the annular edge of the beverage package is placed between the two arms;

[0019] During the process of the first mechanism and the second mechanism closing relative to each other, the second mechanism will drive the beverage package to move forward, so that the annular edge of the beverage package presses the two arms to open the two arms outward, until the second mechanism closes with the first mechanism and the annular edge of the beverage package moves into the interval;

[0020] During the relative opening of the first mechanism and the second mechanism, the beverage package cannot move with the second mechanism because the annular edge is blocked by the blocking portion, and eventually falls under the action of gravity.

[0021] In the beverage extraction device of the present invention, the first part and the second part may be both movable relative to the base, or one part may be fixed relative to the base and the other part may be movable relative to the base; the part with a cavity may be arranged at the front of the base, or the part without a cavity may be arranged at the front of the base. For example, the following structure may be adopted:

[0022] The beverage extraction device of the present invention comprises

[0023] A machine base with a bag loading opening and a bag switching opening;

[0024] A first part and a second part are respectively restrained at the front and rear of the base, wherein the second part can move forward and backward relative to the first part to close or open relative to the first part;

[0025] Features:

[0026] The first mechanism has a cavity for accommodating a beverage package with an annular edge; and the second mechanism is equipped with a release package as described above;

[0027] The base of the release package is fixed relative to the second mechanism, a gap is provided between the stopper portion of the release package and the front end surface of the second mechanism for placing the annular edge of the beverage package, and a clamping opening is formed between the two arms for placing the annular edge of the beverage package;

[0028] When placing the package, the annular edge of the beverage package is placed between the two arms;

[0029] During the process of the first mechanism and the second mechanism closing relative to each other, the second mechanism will drive the beverage package to move forward, so that the annular edge of the beverage package presses the two arms to open the two arms outward, until the second mechanism closes with the first mechanism and the annular edge of the beverage package moves into the interval;

[0030] When the two parts are opened relative to each other, the beverage package will move backwards along with the second part because the annular edge is blocked by the blocking portion, and finally fall down under the action of gravity.

[0031] However, preferably, the first mechanism is fixedly arranged at the front of the base, the second mechanism is arranged at the rear of the base, the release package is fixedly installed relative to the first mechanism, and the second mechanism has the concave cavity; such an arrangement facilitates the installation of the release package.

[0032] The second mechanism comprises a piston, the piston has the concave cavity, and the outer wall of the piston is provided with a concave relief portion adapted to the two arms. The provision of the relief portion can, on the one hand, allow the blocking portion to be closer to the inside, and ensure that the blocking portion can effectively block the annular edge of the beverage package after the extraction is completed, and on the other hand, can reduce or even prevent the wear of the outer wall of the piston caused by the release of the package.

[0033] The base is arc-shaped and is limited by a limiting mechanism to the upper outer surface of the base. The left and right sides of the base are respectively provided with mounting holes for the other parts of the release package to extend into the base. The base is usually an injection molded part. Such a configuration is convenient for both production and installation of the release package.

[0034] The limiting mechanism includes a first stopper provided on the outer surface of the upper part of the base to limit the forward and backward movement of the base, and a second stopper provided on the base to limit the upward and downward movement of the base. During assembly, the base only needs to be clamped between the first stopper and the second stopper, which is convenient, fast and easy to operate. For stable installation, the first stopper and the second stopper can be set in appropriate numbers according to the situation, and they can be spaced at an appropriate distance from each other.

[0035] The second mechanism comprises a piston seat having a piston cavity, wherein the piston is arranged in the piston cavity, and the piston can move forward and backward relative to the piston cavity.

[0036] Compared with the prior art, the advantages of the present invention are:

[0037] The package releasing component includes a base surrounding the outside of the machine base, a blocking portion formed by bending and extending toward the inside of the machine base, and an arm portion formed by bending and extending backwards from the blocking portion. It has a simple structure, involves few parts, is easy to assemble, has good adaptability to existing beverage extraction devices, can effectively realize the package releasing and automatic package removing functions, has strong practicality, and is conducive to reducing the production cost and assembly difficulty of the extraction device.

[0046] The present invention is further described in detail below with reference to the accompanying drawings.

[0047] like Figure 1 FIG. 2 is a preferred embodiment of the package release method of the present invention. Figure 2 to Figure 8 The beverage extraction device is applied with the release package of the embodiment of the present invention.

[0048] The release package A of the embodiment of the present invention is formed by bending a spring steel wire in one piece, and has an arc-shaped base 11, a blocking portion 12 formed by bending and extending the two ends of the base 11 toward each other, and an arm portion 13 formed by bending and extending the end of the blocking portion 12 backward to place the annular edge 31 of the beverage package 3, and a guide portion 14 gradually opens outwards extending from the end of the arm portion 13. In the free state, the distance between the two arms 13 is smaller than the outer diameter of the annular edge 31 of the beverage package and larger than the outer diameter of the beverage package body; when the beverage package 3 is pushed forward, the retaining portion 12 and the arm 13 can be expanded outward under the squeezing action of the annular edge 31, so that the annular edge 31 of the beverage package can move forward from between the two arms 13 and pass over the retaining portion 12; when the retaining portion 12 is in the free state, the outer diameter of the annular edge 31 of the beverage package is larger than the distance between the two inner ends of the retaining portion 12 and smaller than the distance between the two outer ends of the retaining portion 12, and after passing over the retaining portion 12, the annular edge 31 of the beverage package will automatically retract and reset inward under the action of the elastic force of the retaining portion 12 and the two arms 13, so that the annular edge 31 of the beverage package can be blocked by the retaining portion 12 and cannot move backward.

[0049] In this preferred embodiment, the base 11 is used to be fixed around the base 2 of the beverage extraction device. The preferred shape is an arc, and more preferably a semi-arc shape. The simple and symmetrical structure is conducive to production and use. It can be understood that the shape of the base 11 can be matched according to the actual shape of the base 2, and can also be deformed according to actual usage requirements, that is, it can be bent in multiple layers, and can also include other bends.

[0050] The blocking portion 12 is formed by the two ends of the base 11 being bent and extended toward each other, and the bending and extending direction is preferably perpendicular to the end of the base 11. Of course, there may be an angular deviation between the bending and extending direction of the blocking portion 12 and the end of the base 11 within a certain range. For example, the two blocking portions 12 may bend forward or backward at the same time when bending toward each other. As long as the bending and extension can block the annular edge 31 of the beverage package 3, it belongs to the inventive concept of this embodiment and is within the protection scope of the invention.

[0051] See also Figures 2 to 8 As shown, the beverage extraction device of the embodiment of the present invention includes a base 2 with a packing port 21 and a pack switching port 22, a first mechanism 4 fixed at the front of the base 2 and a second mechanism 5 constrained at the rear of the base 2, the second mechanism 5 can move forward and backward relative to the first mechanism 4 to close or open relative to the first mechanism 4, the second mechanism 5 includes a piston seat 51 with a piston cavity 511 and a piston 52 arranged in the piston cavity 511 and able to move forward and backward relative to the piston cavity 511, the piston 52 has a concave cavity 521 for accommodating the beverage bag 3.

[0052] The base of the release package A is fixed relative to the first mechanism 4. After the release package A is assembled, there is a spacing X between the stopper 12 of the release package and the rear end face of the first mechanism 4 for the annular edge 31 of the beverage package 3 to be placed. A clamping opening for placing the annular edge 31 of the beverage package is formed between the two arms 13. When the package is released, the annular edge 31 of the beverage package 3 is placed on the two arms 13. The outer wall of the piston 52 is provided with a concave paving portion 522 adapted to the two arms 13. The distance between the two arms 13 is slightly larger than the distance between the two paving portions 522, so that the piston 52 can pass between the two arms 13 better.

[0053] The base 11 of the release package is installed around the upper outer surface of the base 2, and the left and right sides of the base 2 are respectively provided with mounting holes 23 for the other parts of the release package A to extend inward. Relative to the horizontal axis plane of the first machine part 4, the two mounting holes 23 are slightly biased to the top of the base 2, that is, slightly higher than the horizontal axis plane. Accordingly, the base 11 is generally in an inferior arc shape. On the one hand, when the beverage package 3 is placed, the lower half of the annular edge 31 is placed between the two arms 13, and its tail end is slightly tilted downward, so that the package placement state is more stable. On the other hand, when the beverage package 3 moves forward, the annular edge 31 of the beverage package 3 supports the two arms 13 of the release package.

[0054] In order to stably release the package A, the outer surface of the top of the base 2 is provided with a first stopper 24 for limiting the forward and backward movement of the base 11 and a second stopper 25 for limiting the upward and downward movement of the base 11. Preferably, the second stopper 25 is provided with two spaced apart and symmetrically located on both sides of the first stopper 24 to further enhance the stability of the base 11. Even if the arm 13 is stressed and stretched outward, the base 11 will not deviate. During assembly, the base 11 only needs to be clamped between the first stopper 24 and the second stopper 25, which is convenient, fast and easy to operate.

[0055] The working principle and process of the beverage extraction device of the present invention are as follows:

[0056] Packaging process: The beverage package 3 is loaded from the packing opening 11, and the beverage package 3 falls downward under the action of gravity until the annular edge 31 of the beverage package rests on the two arms 13 of the package release member and is held.

[0057] Package delivery process: The second component 5 moves forward under the drive of the driving mechanism, and the body of the beverage package 3 gradually enters the concave cavity 521 of the second component. When the front annular surface of the piston 52 contacts the annular edge 31 of the beverage package and continues to move forward, the beverage package 3 will be driven forward. During this process, the position of the annular edge 31 of the beverage package will be slightly moved down due to the pressure of the piston 52, and the two arms 13 will be stretched open. Finally, the annular edge 31 of the beverage package will pass over the stopper 12 of the package release and enter the spacing X, and the second component 5 and the first component 4 are sealed and closed. After closing, since the annular edge 31 of the beverage package has entered the spacing X, it no longer exerts a force to stretch the two arms, so the stopper 12 is clamped inward and reset under the action of elastic force and blocked behind the annular edge 31.

[0058] Extraction process: the same as the existing beverage machine (such as coffee machine), no further description is given. In this process, the relative position of the blocking portion 12 and the annular edge 31 remains unchanged.

[0059] Unpacking process: After the extraction is completed, the second mechanism 5 moves backward driven by the driving mechanism. At the beginning, the beverage package 3 moves backward with the second mechanism 5 until the annular edge 31 of the beverage package contacts the blocking portion 12. The second mechanism 5 continues to move backward, and the beverage package 3 no longer moves backward because its annular edge 31 is blocked by the blocking portion 12. Therefore, the body of the beverage package 3 gradually separates from the concave cavity 521. Since in the free state, the distance between the two arms 13 and the distance between the two blocking portions 12 are both greater than the outer diameter of the body of the beverage package, the unpacking component A no longer supports the beverage package 3 at this time. Therefore, the beverage package 3 eventually falls into the waste beverage package box from the package switching port 22 under the action of gravity.
