Description

Technical Field

[0001] The present disclosure relates to the field of beverage equipment, and in particular, to a brewing device and a beverage machine having the same. Background Art

[0002] The brewing device can be used to make beverages such as coffee. The brewing device generally includes a feeder, a brewing cylinder and a piston. The feeder delivers powder or particles to be brewed, such as coffee powder or particles, directly or indirectly into the brewing cylinder. The brewing cylinder and the piston together form a brewing chamber. Liquid flows through the brewing chamber to brew the powder or particles to be brewed in the brewing chamber to obtain a beverage.

[0003] The piston provides at least part of the flow path for guiding the liquid to flow through the brewing chamber, and a filter is usually provided on the piston. After being used for a period of time, residues or grease will be deposited in the flow path and on the filter, which may cause some unintended consequences, such as deterioration of the quality of the beverage. In order to avoid unintended consequences, the piston needs to be regularly maintained.

[0004] During maintenance, the piston needs to be at least partially removed to clean the filter and the flow path. For some brewing devices, the feeder needs to be removed before the piston is removed, and the removal and assembly of the feeder is relatively inconvenient, which makes the maintenance of the piston time-consuming and laborious. Utility Model Content

[0005] In view of this, the present disclosure provides a brewing device and a beverage machine having the same, aiming to improve the problem of time-consuming and labor-intensive piston maintenance work caused by the inconvenient disassembly and assembly of the feeder.

[0006] On the one hand, the present disclosure provides a brewing device. The brewing device includes a frame and a feeder, a brewing cylinder and at least one piston mounted on the frame. The feeder includes a funnel portion for delivering powder or particles directly or indirectly to the brewing cylinder. The brewing cylinder and at least one piston together form a brewing chamber. Liquid flows through the powder or particles located in the brewing chamber to make a beverage. At least one piston provides at least part of a flow path for guiding the liquid to flow through the brewing chamber. The feeder also includes an arm and a first coupling portion fixed to the arm, and the frame includes a second coupling portion. One of the first coupling portion and the second coupling portion is a coupling protrusion, and the other is a coupling recess suitable for receiving the coupling protrusion. The arm is configured to keep the first coupling portion and the second coupling portion coupled when no external force is applied, so as to fix the feeder to the frame. The arm is also configured to drive the first coupling portion and the second coupling portion to separate when an external force is applied, so as to release the feeder.

[0007] According to the brewing device provided by the present disclosure, during the process of disassembling the feeder, it is only necessary to apply an external force to the arm to separate the first combination portion from the second combination portion, thereby releasing the feeder and allowing the feeder to be removed from the frame; during the process of installing the feeder, it is only necessary to move the feeder relative to the frame into position, and the first combination portion will be combined with the second combination portion under the action of the arm, thereby completing the installation of the feeder. It can be seen that the brewing device provided by the present disclosure has the advantage of convenient assembly and disassembly of the feeder. Therefore, using the brewing device provided by the present disclosure helps to reduce the burden of piston maintenance work.

[0008] In a possible implementation, the arm portion is configured to elastically deform and bend outward when subjected to an external force, so as to drive the first combining portion to separate from the second combining portion.

[0009] When the arm is not subjected to external force, the elastic force of the arm keeps the first and second binding parts connected. When subjected to appropriate external force, the arm elastically deforms to separate the first and second binding parts. After the external force is removed, the arm will be reset under the action of its elastic force, thereby driving the first binding part to reset. In this implementation, the function of keeping the first and second binding parts connected is achieved by the elastic force of the arm, and no additional components are used to help achieve this, which is conducive to reducing the number of components of the brewing device, thereby simplifying the structure of the brewing device and reducing the manufacturing cost of the brewing device.

[0010] In a possible implementation, the feeder further includes a gripping portion, which is fixed to the arm and configured to be gripped by an operator's hand so as to transfer an external force from the hand to the arm.

[0011] In this implementation, the operator only needs to hold the grip and apply an appropriate external force to cause the arm to elastically deform to release the feeder without the need for additional tools. This shows that this implementation can further improve the convenience of the feeder disassembly and assembly process, thereby further reducing the burden of piston maintenance work.

[0012] In one possible implementation, the arm portion is displaceable between a combined position and a released position. When the arm portion is in the combined position, the first combined portion and the second combined portion are combined. When the arm portion is in the released position, the first combined portion and the second combined portion are separated. The feeder also includes a force applying member, which applies a force to the arm portion to keep it in the combined position.

[0013] When the arm is not subjected to external force, the force applied from the force-applying member keeps the arm in the combined position, so that the first combined portion and the second combined portion remain combined. When the arm is subjected to an appropriate external force, the arm will overcome the force applied from the force-applying member under the action of the external force and move to the release position, thereby separating the first combined portion and the second combined portion. After the external force is removed, the arm will be reset to the combined position under the action of the force applied from the force-applying member. In this implementation, the separation of the first combined portion and the second combined portion does not rely on the deformation of the arm, which is conducive to improving the durability of the arm.

[0014] In a possible implementation, the feeder further comprises a support portion, the arm portion is pivotally supported by the support portion around an axis so as to be displaced between a coupling position and a release position by pivoting. The arm portion comprises a pressing portion for an operator to press with his hand, and the pressing portion and the first coupling portion are respectively located on opposite sides of the axis.

[0015] According to this structure of the feeder, the operator only needs to press the pressing part to release the feeder. It can be seen that this implementation method can further improve the convenience of the feeder disassembly process, thereby further reducing the maintenance burden of the piston.

[0016] In a possible implementation, the feeder further includes a first guide portion, and the frame further includes a second guide portion. One of the first guide portion and the second guide portion is a guide recess extending in the up-down direction, and the other is a guide protrusion extending in the up-down direction. The guide recess is configured to receive the guide protrusion so that the feeder can be mounted to the frame or removed from the frame by moving in the up-down direction relative to the frame. The first binding portion is configured to be combined with the second binding portion to limit the movement of the feeder in the up-down direction relative to the frame.

[0017] In the process of disassembling the feeder, an external force can be first applied to the arm to separate the two coupling parts to allow the feeder to move downward (or upward) relative to the frame; then, the feeder can be moved downward (or upward) relative to the frame to separate the first guide part and the second guide part, and then the feeder can be removed from the frame. In the process of installing the feeder, it is only necessary to move the feeder upward (or downward) relative to the frame so that the feeder moves into place under the guidance of the two guide parts, and the first coupling part and the second coupling part will automatically combine to limit the movement of the feeder relative to the frame in the up and down directions, thereby completing the assembly of the feeder. According to the coupling part and the guide part with the above-mentioned structure, the feeder can be reliably fixed on the frame, and the disassembly and assembly of the feeder is also relatively convenient.

[0018] In a possible implementation, the arm portion is disposed on the first guide portion, and the second combining portion is disposed on the second guide portion.

[0019] The arm portion and the first coupling portion located on the first guide portion and the second coupling portion located on the second guide portion will not occupy additional space, which is beneficial to improving the structural compactness of the feeder and the frame.

[0020] In a possible implementation, the first combining portion is a combining convex portion, and the second combining portion is a combining concave portion.

[0021] Considering that the frame is usually made of metal, while the feeder is usually made of polymer material (such as plastic), it is more cost-effective to provide a coupling recess on the frame and a coupling protrusion on the feeder.

[0022] In a possible implementation manner, the first guide portion is a guide recess, and the second guide portion is a guide protrusion.

[0023] The implementation method of providing the guide recess on the feeder and the guide protrusion on the frame can help the feeder to obtain a relatively thin structure. In the implementation method in which the arm is provided on the first guide part, the relatively thin feeder is conducive to reducing the difficulty of implementing the arm and the first joint part.

[0024] In a possible implementation, the frame is provided with two second guides on opposite sides thereof, and the feeder includes two opposite first guides. The two first guides are configured to cooperate with the two second guides respectively. The feeder is provided with two arms and two first binding parts respectively fixed to the two arms, the frame is provided with two second binding parts respectively combined with the two first binding parts, the two arms are respectively provided on the two first guides, and the two second binding parts are respectively provided on the two second guides.

[0025] The feeder can be more securely mounted on the frame through the two first combining portions, the two second combining portions, the two first guiding portions, and the two second guiding portions.

[0026] In a possible implementation, the brewing device further includes a channel member, the channel member is configured to guide the powder or particles to slide from the lower end outlet of the feeder to the upper end inlet of the brewing cylinder, and the channel member is mounted on the feeder.

[0027] Considering that the channel piece will also hinder the removal of the piston, the channel piece needs to be removed before the piston is removed. In the current implementation of the present disclosure, the channel piece is installed on the feeder, so the feeder and the channel piece can be removed together only by removing the feeder from the frame, which can further improve the convenience of the feeder disassembly process, thereby further reducing the burden of piston maintenance work.

[0028] On the other hand, the present disclosure further provides a beverage machine, which includes the above-mentioned brewing device. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in a variety of ways and should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and clear understanding of the present disclosure.

[0045] The present disclosure provides a brewing device 100. The brewing device 100 is used to make beverages, such as coffee. The brewing device 100 can be used alone or as a functional unit in a beverage machine, such as a coffee machine. It is understood that the brewing device 100 is not limited to making coffee, and can also be used to make other types of beverages. The present disclosure does not specifically limit the type of beverage made by the brewing device 100.

[0046] refer to Figure 1 The brewing device 100 may include a frame 10, an upper piston 20, a lower piston 30, a brewing cylinder 40, a driving device 50, a transmission mechanism 60, and a feeder 70. The upper piston 20, the lower piston 30, the brewing cylinder 40, the driving device 50, the transmission mechanism 60, and the feeder 70 may be mounted on the frame 10 to be supported by the frame 10.

[0047] The driving device 50 can output power, which is transmitted to the brewing cylinder 40 via the transmission mechanism 60, so that the brewing cylinder 40 moves in the up-down direction relative to the upper piston 20. For example, the driving device 50 can be a motor, and the transmission mechanism 60 can be a screw transmission mechanism. The upper end of the lower piston 30 can extend into the brewing cylinder 40 to close the bottom end of the brewing cylinder 40. As the brewing cylinder 40 moves in the up-down direction, it will move with the lower piston 30.

[0048] The feeder 70 may include a funnel portion 71, which defines a feeding channel in the shape of a funnel with a large upper end and a small lower end. Figure 1 When the upper piston 20 is in the middle position, the upper piston 20 is separated from the brewing cylinder 40, and the top of the brewing cylinder 40 is opened. At this time, the powder or particles to be brewed (such as coffee powder or particles) can be poured into the feeding channel from the top of the feeder 70, and then directly or indirectly guided into the brewing cylinder 40 by the feeding channel.

[0049] After the powder or granules to be brewed are added, the driving device 50 drives the brewing cylinder 40 to rise through the transmission mechanism 60. As the brewing cylinder 40 rises, the lower end of the upper piston 20 extends into the brewing cylinder 40 to form a substantially closed brewing chamber together with the brewing cylinder 40 and the lower piston 30. Then, liquid (for example, hot water) flows through the brewing chamber and flows through the powder or granules to be brewed, thereby producing a beverage. The brewed beverage can be taken and drunk directly, or it can be drunk after further processing.

[0050] The flow path for guiding the liquid to flow through the brewing chamber may be provided at least in part by the upper piston 20 and the lower piston 30. For example, a pipe and a filter may be provided in the lower piston 30, the pipe defining a flow path portion for introducing the liquid into the brewing chamber, and the liquid may flow into the brewing chamber through the pipe and the filter in sequence. For another example, the upper piston 20 may also be provided with a pipe and a filter, the pipe defining a flow path portion for guiding the obtained beverage out of the brewing chamber, and the beverage may flow out of the brewing chamber through the filter and the pipe in sequence.

[0051] When the brewing device 100 is applied to a beverage machine, the beverage machine may be provided with a grinding device, and the outlet of the grinding device may be located above the feeder 70. The grinding device may grind raw materials (e.g., coffee beans) into powder or particles to be brewed. The feeder 70 may be used to receive the powder or particles from the grinding device and deliver the powder or particles directly or indirectly to the brewing cylinder 40.

[0052] Continue to refer Figure 1 The brewing device 100 may further include a residue pusher 80. After brewing is completed, the brewing cylinder 40 will descend with the lower piston 30. After descending to a lower position, the lower piston 30 is blocked and stops. As the brewing cylinder 40 descends to the lowest position, the lower piston 30 pushes the waste residue out of the brewing cylinder 40, and then the residue pusher 80 is driven to pivot, thereby pushing the waste residue and causing the waste residue to fall from the top of the brewing cylinder 40.

[0053] It should be understood that the above is only an example of the brewing device 100, and the brewing device 100 is not limited to the above. For example, in some examples, the brewing device 100 may include only the upper piston 20 but not the lower piston 30. In this case, the bottom end of the brewing cylinder 40 may have a bottom sealing structure. For another example, in some examples, the brewing chamber 40 may be fixed, and the driving device 50 may drive the upper piston 20 to move up and down.

[0054] After a period of use, residue or grease may be deposited on the filter screen and flow path of the upper piston 20 and / or the lower piston 30, which may cause some unexpected consequences, such as deteriorating the quality of the beverage. In order to avoid unexpected consequences, at least part of the upper piston 20 and / or the lower piston 30 needs to be removed for cleaning. However, before removing the upper piston 20 and / or the lower piston 30, the feeder 70 needs to be removed.

[0055] In order to facilitate the disassembly and installation of the feeder 70, the present disclosure improves the frame 10 and the feeder 70. The improved parts will be described below with reference to the accompanying drawings.

[0056] refer to Figures 2 to 6, the feeder 70 may further include an arm 72 and a first combining portion 73, and the first combining portion 73 is fixed to the arm 72. The first combining portion 73 may be formed integrally with the arm 72, or may be mounted on the arm 72. The frame 10 may include a second combining portion 11. In the current example, the first combining portion 73 is a combining protrusion, and the second combining portion 11 is a combining recess suitable for receiving the combining protrusion. In other examples, the first combining portion 73 may be a combining recess, and the second combining portion 11 may be a combining recess. Considering that the frame is usually made of metal, and the feeder is usually made of polymer material (such as plastic), the implementation method of providing a combining recess on the frame and providing a combining protrusion on the feeder is more cost-effective.

[0057] The arm portion 72 is configured to keep the first coupling portion 73 coupled with the second coupling portion 11 when no external force is applied, that is, to keep the coupling protrusion at least partially located in the coupling recess, so as to fix the feeder 70 to the frame 10. The arm portion 72 is also configured to drive the first coupling portion 73 to separate from the second coupling portion 11 when subjected to a suitable external force, that is, to bring the coupling protrusion out of the coupling recess, so as to release the feeder 70.

[0058] For example, in the current example, a tool can be used to pry the arm 72 to apply external force thereto. For example, the tool can be a screwdriver. Of course, other types of tools can also be used.

[0059] According to the brewing device 100 provided by the present disclosure, during the process of disassembling the feeder 70, it is only necessary to apply an external force to the arm 72 to separate the first coupling portion 73 from the second coupling portion 11, thereby releasing the feeder 70 and allowing the feeder 70 to be removed from the frame 11; during the process of installing the feeder 70, it is only necessary to move the feeder 70 relative to the frame 10, and the first coupling portion 73 will be combined with the second coupling portion 11 under the action of the arm 72, thereby completing the installation of the feeder 70. It can be seen that the brewing device 100 provided by the present disclosure has the advantage of convenient disassembly and assembly of the feeder 70. Therefore, the use of the brewing device 100 provided by the present disclosure helps to reduce the burden of maintenance work on the upper piston 20 and the lower piston 30.

[0060] refer to Figure 3 In the current example, the arm portion 72 may be configured to elastically deform and bend outward when subjected to an external force, so as to drive the first coupling portion 73 to separate from the second coupling portion 11. Figure 3 , the arm portion 72 when not subjected to external force and the arm portion 72 elastically deformed by the external force are shown at the same time, and the first joint portion 73 in the two cases is shown accordingly. Here, the solid line shows the arm portion 72 and the first joint portion 73 when not subjected to external force, and the dotted line shows the arm portion 72 and the first joint portion 73 when subjected to external force.

[0061] When the arm 72 is not subjected to an external force, the elastic force of the arm 72 keeps the first binding portion 73 and the second binding portion 11 connected. When subjected to an appropriate external force, the arm 72 elastically deforms to separate the first binding portion 73 and the second binding portion 11. After the external force is removed, the arm 72 will be reset under the action of its elastic force, thereby driving the first binding portion 73 to reset. In this implementation, the function of keeping the first binding portion 73 and the second binding portion 11 connected is achieved by the elastic force of the arm 72, and no additional components are used to help achieve it, which is conducive to reducing the number of components of the brewing device 100, and is conducive to simplifying the structure of the brewing device 100 and reducing the manufacturing cost of the brewing device 100.

[0062] refer to Figures 4 to 7 The feeder 70 may further include a first guide portion 74, and the frame 11 may further include a second guide portion 12. In the current example, the first guide portion 74 is a guide recess extending in the up-down direction, and the second guide portion 12 is a guide protrusion extending in the up-down direction, and the guide recess is suitable for receiving the guide protrusion. When the feeder 70 is moved in the up-down direction relative to the frame 11, the guide protrusion can slide in the guide recess.

[0063] In the process of disassembling the feeder 70, an external force can be applied to the arm 72 first, so that the first combination part 73 and the second combination part 11 are separated to allow the feeder 70 to move downward (or upward) relative to the frame 10; then, the feeder 70 can be moved downward (or upward) relative to the frame 11 to separate the first guide part 74 and the second guide part 12, and the feeder 70 can be removed from the frame 10. In the process of installing the feeder 70, it is only necessary to move the feeder 70 upward (or downward) relative to the frame 10, so that the feeder 70 moves into place under the guidance of the first guide part 74 and the second guide part 12, and the first combination part 73 and the second combination part 11 will automatically combine to limit the movement of the feeder 70 relative to the frame 10 in the up and down directions, thereby completing the assembly of the feeder 70. According to the first combination part 73 and the second combination part 11 and the first guide part 74 and the second guide part 12 having the above-mentioned structure, the feeder 70 can be reliably fixed on the frame 10, and the disassembly and assembly of the feeder 70 is also relatively convenient.

[0064] Continue to refer Figures 4 to 7 , the arm 72 may be disposed on the first guide portion 74, and the second coupling portion 11 may be disposed on the second guide portion 12. For example, in the current example, the arm 72 may also be formed integrally with the first guide portion 74. Of course, in other examples, the arm 72 may be an independent component, which may be mounted on the first guide portion 74. The arm 72 and the first coupling portion 73 located on the first guide portion 74 and the second coupling portion 11 located on the second guide portion 12 will not occupy additional space, which is conducive to improving the compactness of the structure of the feeder 70 and the frame 10.

[0065] It should be noted that, although in the above examples, the first guide portion 74 is a guide recess and the second guide portion 12 is a guide protrusion, in other examples, the first guide portion 74 may be a guide protrusion and the second guide portion 12 may be a guide recess. The implementation method of providing the guide recess on the feeder 70 and providing the guide protrusion on the frame 10 can help the feeder 70 to obtain a relatively thin structure. In the implementation method in which the arm portion 72 is provided on the first guide portion 74, the thinner feeder 70 is conducive to reducing the difficulty of implementing the arm portion 72 and the first coupling portion 73.

[0066] Continue to refer Figures 4 to 7 , the frame 10 may be provided with two second guide portions 12 on opposite sides thereof, respectively, and the feeder 70 may include two opposite first guide portions 74. The two first guide portions 74 are configured to cooperate with the two second guide portions 12, respectively. The feeder 70 is provided with two arms 72 and two first coupling portions 73 respectively fixed on the two arms 72. The frame 10 is provided with two second coupling portions 11 respectively coupled with the two first coupling portions 73, the two arms 72 are respectively provided on the two first guide portions 74, and the two second coupling portions 11 are respectively provided on the two second guide portions 12. Through the two first coupling portions 73, the two second coupling portions 11, the two first guide portions 74 and the two second guide portions 12, the feeder 70 can be more securely mounted on the frame 10.

[0067] Back to Figure 1 The brewing device 100 may further include a channel member 90, which is provided with a guide channel. The powder or particles to be brewed can slide from the lower end outlet of the feeding channel of the feeder 70 to the upper end inlet of the brewing cylinder 40 through the guide channel. In other words, the feeder 70 indirectly delivers the powder or particles to be brewed to the brewing cylinder 40. The channel member 90 may be mounted on the feeder 70. For example, the channel member 90 may be fixed to the feeder 70 by an interlocking manner, or may be fixed to the feeder 70 by a fastener.

[0068] Considering that the channel member 90 will also hinder the disassembly of the upper piston 20 and the lower piston 30, the channel member 90 needs to be removed before disassembling the upper piston 20 and the lower piston 30. In the current implementation of the present disclosure, the channel member 90 is installed on the feeder 70, so the feeder 70 and the channel member 90 can be removed together by only removing the feeder 70 from the frame 10, which can further improve the convenience of the disassembly process of the feeder 70, thereby further reducing the maintenance workload of the upper piston 20 and the lower piston 30.

[0069] It should be noted that, although in the current example, the powder or particles to be brewed are delivered to the brewing cylinder via the feeder 70 and the channel member 90 in sequence, in other examples, the brewing device 100 may not include the channel member 90, and the funnel portion 71 of the feeder 70 may extend downward to the upper end of the brewing cylinder 40, thereby directly delivering the powder or particles to be brewed into the brewing cylinder 40.

[0070] Below, the feeder 70a and the feeder 70b according to the modified example of the present disclosure are illustrated. The feeder 70a and the feeder 70b according to the modified example are substantially the same as the feeder 70 in the above text, and they have many identical or similar elements. For the purpose of brevity, in this article, the same or similar elements will be marked with the same reference numerals to appropriately omit repeated descriptions.

[0071] refer to Figure 8 and Fig. 9 The feeder 70a provided in the modification example 1 of the present disclosure may further include a gripping portion 75. The gripping portion 75 may be fixed to the arm portion 72 and configured to be gripped by the operator's hand so as to transfer the external force from the hand to the arm portion 72. The gripping portion 75 may be formed integrally with the arm portion 72 or may be mounted on the arm portion 72.

[0072] In this implementation, the operator only needs to hold the grip 75 and apply an appropriate external force to cause the arm 72 to elastically deform to release the feeder 70a without the need for additional tools. It can be seen that this implementation can further improve the convenience of the disassembly and assembly process of the feeder 70a, thereby further reducing the maintenance workload of the upper piston 20 and the lower piston 30.

[0073] It should be noted that the present disclosure does not impose any specific limitation on the structure of the grip portion 75 , as long as it can be gripped by the operator's hand to transmit the external force from the hand to the arm portion 72 .

[0074] refer to Fig.10 and Fig.11 In variation 2 of the present disclosure, the arm 72b of the feeder 70b is an independent component, which is mounted on other parts of the feeder 70b, for example, on the first guide portion 74. The arm 72b is capable of displacement between a coupling position and a release position. When the arm 72b is in the coupling position, the first coupling portion 73 and the second coupling portion 11 are coupled. When the arm 72b is in the release position, the first coupling portion 73 and the second coupling portion 11 are separated. The feeder 70b may further include a force applying member 76, which applies a force to the arm 72b to keep it in the coupling position.

[0075] When the arm 72b is not subjected to external force, the force applied by the force applying member 76 keeps the arm 72b in the combined position, so that the first combined portion 73 and the second combined portion 11 remain combined. When the arm 72b is subjected to an appropriate external force, the arm 72b will overcome the force applied by the force applying member 76 under the action of the external force and move to the release position, thereby separating the first combined portion 73 and the second combined portion 11. After the external force is removed, the arm 72b will be reset to the combined position under the action of the force applied by the force applying member 76. In this implementation, the separation of the first combined portion 73 and the second combined portion 11 does not rely on the deformation of the arm 72b, which is conducive to improving the durability of the arm 72b.

[0076] Continue to refer Fig.10 and Fig.11 The feeder 70b may further include a support portion 77, and the arm portion 72b is pivotally supported by the support portion 77 around an axis to move between the engagement position and the release position by pivoting. The arm portion 72b may include a pressing portion 721 for the operator to press. The pressing portion 721 and the first engagement portion 73 are respectively located on opposite sides of the axis A.

[0077] According to the structure of the feeder 70b, the operator can release the feeder 70b by only pressing the pressing portion 721. It can be seen that this implementation can further improve the convenience of the disassembly and assembly process of the feeder 70b, thereby further reducing the maintenance burden of the upper piston 20 and the lower piston 30.

[0078] As a possible implementation, the force applying member 76 can be implemented as a compression spring 76, which can be located between the pressing portion 721 and the first guide portion 74. More specifically, a convex column 78 can be provided on the outer side of the first guide portion 74, and a convex column (not shown) is also provided on the inner side of the pressing portion 721. One end of the compression spring 76 can be sleeved on the convex column 78 on the outer side of the first guide portion 74, and the other end can be sleeved on the convex column (not shown) on the pressing portion 721.

[0079] It is understandable that there are many ways to implement the force-applying member 76, and it is not limited to a compression spring. The present disclosure does not place any particular restrictions on the implementation of the force-applying member 76, as long as it can apply a force to the arm portion 72b to keep it in the combined position. For example, in an alternative example, the force-applying member 76 can be implemented as a torsion spring. For example, in another alternative example, the force-applying member 76 can be implemented as a pair of oppositely polarized magnetic members.

[0080] As a possible implementation, the support portion 77 may be implemented as a pair of lug portions 77 arranged at intervals, each lug portion 77 being provided with an axis hole. Correspondingly, the arm portion 72b may be provided with a pair of colinear rotating shafts 722 on both sides thereof, and the pair of rotating shafts 722 are respectively inserted into the pair of axis holes, so that the arm portion 72b is pivotally supported by the support portion 77. In this implementation, the axis A is defined by the pair of rotating shafts 722.

[0081] The present disclosure also provides a beverage machine, which may include a brewing device provided by the present disclosure. In some examples, the beverage machine may be a coffee machine for making coffee. Of course, in other examples, the beverage machine may also be used for making other beverages.

[0082] It should be noted that the various elements described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0083] It should be understood that multiple components and / or parts can be provided by a single integrated component or part. Alternatively, a single integrated component or part can be divided into separate multiple components and / or parts. The disclosure "one" or "an" used to describe a component or part is not intended to exclude other components or parts.

[0084] It should be understood that although the terms "first" or "second" etc. may be used in the present disclosure to describe various elements (such as a first combining portion and a second combining portion), these elements are not defined by these terms, and these terms are only used to distinguish one element from another.

[0085] The protection scope of the present disclosure is not limited to the above-mentioned embodiments. Any changes or substitutions that can be conceived by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
