Description

Technical Field

[0001] This utility model belongs to the field of coffee equipment, specifically relating to a coffee filtration device and a coffee machine. Background Technology

[0002] In existing coffee machines, different types of beverages, such as espresso, Americano, and cold brew, require different coffee powder holding volumes, pressure tolerance, and flow rate control precision. Therefore, they typically need at least two filter holders and matching filter cups for dispensing coffee, or different machines are required to make different types of coffee. Current technology generally identifies different filter holders through simple visual identification, specifically by coloring the handle of the filter holder according to its type. Using color to visually distinguish different filter holders and filter cups for different beverages can easily lead to problems such as mismatched water volume and excessive pressure causing filter damage, resulting in a decrease in the beverage extraction success rate and quality. Furthermore, since different beverages require different sized filter holders and filter cups, or different machines, the equipment cost is high, and the numerous and scattered parts are difficult to organize properly, easily leading to loss. Utility Model Content

[0003] The purpose of this invention is to provide a coffee filtering device that can quickly distinguish different filter cups and adapt to the different beverages made with the corresponding filter cups.

[0004] The following technical solutions are used to achieve the above objectives.

[0005] The first aspect of this utility model provides a coffee filtering device, which includes a filter cup support and a plurality of filter cup components; each filter cup component includes a fixing member and a filter cup, the fixing member is connected to the filter cup, and the filter cup is detachably mounted on the filter cup support via the fixing member; the fixing member is provided with a protrusion, and each filter cup component corresponds to a different height, or the fixing member in each filter cup component corresponds to a protrusion at a different position.

[0006] In some embodiments, the protrusions in each of the filter cups are located at different positions in the circumferential direction of the fixing member.

[0007] In some embodiments, the protrusion is a magnetic element disposed on the fixing element, and the position of the magnetic element corresponding to the fixing element in each filter cup is different.

[0008] In some embodiments, the magnetic elements in each of the filter cups are disposed at different positions in the circumferential or axial direction of the fixing member.

[0009] In some embodiments, the protrusion is a magnetic element disposed on the fixing element, and the height of the magnetic element corresponding to the fixing element in each filter cup is different.

[0010] In some embodiments, the fastener is a ring-shaped structure and is sleeved on the filter cup. A support portion is formed between the inner and outer ring edges of the fastener, and the support portion is detachably mounted on the filter cup support.

[0011] In some embodiments, the fixing member is provided with a first limiting member, and the filter cup bracket is provided with a second limiting member. The fixing member is detachably mounted on the filter cup bracket by the limiting cooperation of the first limiting member and the second limiting member.

[0012] In some embodiments, the first limiting member is a limiting block or limiting groove disposed on the outer ring edge of the fixing member, and the second limiting member is a limiting groove or limiting block disposed on the edge of the filter cup support.

[0013] The second aspect of this utility model provides a coffee machine, which includes a machine body and a coffee filter device as described above. The machine body is provided with a filter position, the filter cup holder is detachably disposed at the filter position, and the machine body is provided with an identification device corresponding to the position of the filter position.

[0014] When the fixing member is mounted on the filter cup bracket and the filter cup bracket is mounted on the filter position, the identification device identifies the filter cup or the protrusion.

[0015] In some embodiments, the coffee machine further includes a safety circuit for controlling the start and stop of the machine body, wherein the safety circuit is activated by the identification device to identify the filter cup or the protrusion to control the start of the machine body.

[0016] The technical solution provided by this utility model has the following advantages and effects:

[0017] This coffee filtration device connects to the filter cup via a fixing component, forming a single filter cup unit. Each filter cup corresponds to a different height, or each fixing component has a protrusion at a different position from other fixing components that indicates the type of filter cup. Therefore, by identifying the height of the filter cup or the position of the protrusion on the fixing component, the type of filter cup can be identified. Based on the identified filter cup type, the corresponding beverage type can be prepared, effectively avoiding problems such as mismatched water volume and excessive pressure causing filter screen damage. This improves the beverage extraction pass rate and reduces the decline in extraction quality. Furthermore, the filter cup can be detachably connected to the filter cup holder via the fixing component, requiring only one filter cup holder to accommodate different types of filter cups. This eliminates the need for multiple filter cup holders, greatly reducing costs and the types and number of equipment components, and facilitating storage and organization.

[0034] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0035] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0036] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0037] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0038] This utility model embodiment provides a coffee filtering device 10, such as Figures 1 to 11As shown, the coffee filtering device 10 includes a filter cup holder 1 and multiple filter cup components 2; each filter cup component 2 includes a fixing member 21 and a filter cup 22, the fixing member 21 being connected to the filter cup 22, and the filter cup 22 being detachably mounted on the filter cup holder 1 via the fixing member 21. It should be noted that this coffee filtering device 10 can be assembled onto a coffee machine for coffee filtering and extraction. The coffee machine body has conventional components for coffee extraction, such as nozzles and control panels. Since these are not the focus of this utility model and are conventional technologies, they will not be described in detail here. The coffee machine body also has a filter position, which can be a U-shaped locking position formed by a suspended block. The filter cup holder 1 can be detachably suspended on the U-shaped locking position of the machine body for assembly on the coffee machine for coffee filtration and extraction. Of course, in other embodiments, the structure of the machine body for supporting the filter cup holder is not limited to the U-shaped locking position; it can also be two or three or more inwardly snapping structures. No special limitation is made here.

[0039] The fixing member 21 is provided with a protrusion 211, and each of the filter cups 2 corresponds to a different height, or the fixing member 21 in each of the filter cups 2 corresponds to a protrusion 211 at a different position. It should be noted that each filter cup 22 is equipped with a fixing member 21, wherein the fixing member 21 can be a structure that is fixedly connected to the filter cup 22 or a structure that is detachably connected. There is no particular limitation here. When the filter cup 22 and the fixing member 21 are connected as a whole to form a filter cup 2, the different heights of the filter cup 2 or the different positions of the protrusions 211 on the fixing member 21 represent the type of filter cup 22 to which it is connected. Different filter cups 22 correspond to different overall heights of filter cup 2 or different positions of the protrusions 211. Therefore, by identifying the height of the filter cup 2 or the protrusions 211 on the fixing member 21, the type of filter cup 22 can be identified.

[0040] Therefore, it is understandable that the coffee filtering device 10 is connected to the filter cup 22 by setting a fixing member 21, so that the fixing member 21 and the filter cup 22 cooperate to form a filter cup component 2 as a whole. Each filter cup component 2 corresponds to a different height, or each fixing member 21 is provided with a protrusion 211 at a different position from other fixing members 21, which can indicate the type of filter cup 22. Therefore, by identifying the height of the filter cup component 2 or the position of the protrusion 211 on the fixing member 21, the type of filter cup 22 can be identified. Based on the identified type of filter cup 22, the corresponding type of beverage can be prepared, effectively avoiding problems such as mismatch of water volume and pressure exceeding the limit to break the filter screen, improving the beverage extraction qualification rate and reducing the decline in extraction quality. Moreover, the filter cup 22 can be detachably connected to the filter cup support 1 through the fixing member 21, so only one filter cup support 1 is needed to adapt to different types of filter cup components 2, eliminating the need to set multiple filter cup supports 1, which can greatly reduce costs and the types and quantities of equipment components, and facilitate storage and organization.

[0041] Specifically, such as Figure 3 and Figure 4 As shown, each of the filter cups 2 corresponds to a different height, and each type of filter cup 22 corresponds to a unique height of filter cup 2. For example, the height of the filter cup 2 corresponding to the small filter cup 22 is lower than the height of the filter cup 2 corresponding to the large filter cup 22. The identification device 20 includes a trigger rod 201 and multiple identification switches 202. The trigger rod 201 is movably mounted on the machine body of the coffee machine, and each identification switch 202 is located at a different height position along the movement trajectory of the trigger rod 201. Therefore, when filter cups 2 of different heights are loaded into the filter position of the machine body, the protrusion 211 on the filter cup 2 can abut against the trigger rod 201 and drive the trigger rod 201 to move, thereby moving the trigger rod 201 to contact the identification switch 202 that is adapted to the height of the filter cup 2, thereby identifying the type of filter cup 22 and accurately selecting the corresponding beverage type for preparation. For ease of understanding, as shown... Figure 3 and Figure 4 As shown, Figure 3 The middle part is the small filter cup 2, therefore its height is low. It moves the actuating rod 201 to contact only the left-side identification switch 202, while disengaging from the right-side identification switch 202. Figure 4 The larger filter cup 2 is taller, and its actuation rod 201 moves to contact the identification switches 202 on the left and right sides respectively, thus generating a different identification signal than that of the smaller filter cup 2, thereby identifying and distinguishing the type of filter cup 22. Specifically, the identification switch 202 can be a micro switch or a contact switch, etc. The identification switch 202 is not limited to the type described above; other types of switches capable of identifying the height of the actuation rod 201 can also be used.

[0042] In some embodiments, such as Figures 5 to 6 As shown, the protrusions 211 in each of the filter cup components 2 are disposed at different positions in the circumferential direction of the fixing member 21. The filter cups 22 are distinguished by identifying the specific positions of each protrusion 211. Specifically, by setting protrusions 211 at different positions in the circumferential direction of the fixing member 21, each type of filter cup 22 corresponds to a unique position of protrusion 211. An identification device 20 is respectively provided on the machine body at the position corresponding to each protrusion 211. Each identification device 20 includes a trigger rod 201 and an identification switch 202, wherein the trigger rod 201 is movably disposed on the machine body of the coffee machine, and the identification switch 202 is disposed on the movement trajectory of the trigger rod 201. Therefore, when the fixing member 21 is mounted on the filter cup holder 1 and the filter cup holder 1 is mounted on the filter position, the protrusion 211 abuts against the corresponding trigger rod 201 and drives the trigger rod 201 to move, thereby causing the trigger rod 201 to move to contact the identification switch 202. The identification switch 202 identifies the specific position of the protrusion 211, thereby distinguishing the filter cup 22. The coffee machine selects the corresponding beverage type for preparation based on the identified filter cup 22 type. Specifically, the identification switch 202 can be a micro switch or a contact switch, etc., without any particular limitation.

[0043] In some embodiments, such as Figures 7 to 10 As shown, the protrusion 211 is a magnetic component disposed on the fixing component 21. The magnetic components corresponding to the fixing components 21 in each filter cup 2 have different positions or heights. The positions of the magnetic components are identified to distinguish each filter cup 22. Specifically, by setting magnetic components at different positions or heights on the fixing component 21, each type of filter cup 22 corresponds to a unique magnetic component at a unique position or height. The identification device 20 is a magnetic suction component or a corresponding magnetic switch disposed on the machine body that is adapted to the position or height of each magnetic component and is magnetically attracted to it. The magnetic switch can be turned on when it senses magnetism. When the fixing component 21 is mounted on the filter cup holder 1 and the filter cup holder 1 is mounted on the filter position, the magnetic component and the corresponding magnetic suction component magnetically attract each other to generate a corresponding signal, thereby distinguishing the filter cup 22. The coffee machine selects the corresponding beverage type for preparation based on the identified filter cup 22 type. Specifically, the magnetic elements in each of the filter cup components 2 are disposed at different positions in the circumferential direction of the fixing member 21; and / or, the magnetic elements in each of the filter cup components 2 are disposed at different positions in the axial direction of the fixing member 21, so as to distinguish the types of filter cups 22 by differentiating the positions of the magnetic elements in the circumferential or axial directions of the fixing member 21.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixing member 21 has a ring-shaped structure and is sleeved on the filter cup 22. A support portion is formed between the inner and outer ring edges of the fixing member 21, and the support portion is detachably mounted on the filter cup support 1. Since the fixing member 21 is the connecting component between the filter cup support 1 and different types of filter cups 22, the fixing member 21 in different filter cup components 2 can be adapted to the shape of the filter cup 22, exhibiting high adaptability and flexibility. Its structure is not fixed but can be customized according to the external contour of the specific filter cup 22 to be installed. Furthermore, the fixing member 21 is configured as a ring structure, which can be tightly fitted onto the outer periphery of the filter cup 22 to form a stable connection. This allows the filter cup support 1 to be securely assembled with various types and shapes of filter cups 22. At the same time, the body structure between its inner and outer ring edges forms a support portion mounted on the filter cup support 1, thereby establishing a stable, reliable, and adaptable mechanical connection bridge between the filter cup 22 and the filter cup support 1. Therefore, it is not necessary to set up multiple filter cup supports 1 to work with different types of filter cups 22. Only one filter cup support 1 is needed to adapt to different types of filter cups 22, which can greatly reduce costs and the types and quantities of equipment components, and facilitate storage and organization.

[0045] In some embodiments, such as Figure 1 and Figure 2As shown, the fixing member 21 is provided with a first limiting member 212, and the filter cup support 1 is provided with a second limiting member 11. The fixing member 21 is detachably mounted on the filter cup support 1 through the limiting cooperation of the first limiting member 212 and the second limiting member 11. The limiting cooperation of the first limiting member 212 and the second limiting member 11 ensures a stable connection between the fixing member 21 and the filter cup support 1, guaranteeing that the fixing member 21 and the filter cup 22 fixed inside it can be accurately placed in the preset correct position on the filter cup support 1, while also facilitating disassembly, maintenance, or replacement of the filter cup 22. Specifically, a first limiting member 212 can be provided at a specific location on the fixing member 21, such as the outer ring edge, bottom, or side wall of the fixing member 21, where it contacts the filter cup holder 1. This first limiting member 212 can be one or more, such as a protruding buckle, positioning pin, groove, specific flange structure, or guide groove. Correspondingly, a second limiting member 11 is provided on the filter cup holder 1 at a position matching the first limiting member 212. This second limiting member 11 can be a slot, positioning hole, matching flange, recess forming a constraint with the flange, guide rail, etc., adapted to the first limiting member 212, without any particular limitation. Specifically, in this embodiment, the first limiting member 212 is a limiting block or limiting groove provided on the outer ring edge of the fixing member 21, and the second limiting member 11 is a limiting groove or limiting block provided on the edge of the filter cup holder 1. Through the cooperative use of the limiting block and the limiting groove, quick assembly and disassembly can be performed, and it has the characteristics of simple structure and stable connection.

[0046] This utility model provides a coffee machine, which includes a machine body and a coffee filter device 10 as described above.

[0047] The machine body has a filter position, and the filter cup support 1 is detachably mounted on the filter position. The machine body is equipped with an identification device 20 corresponding to the position of the filter position. The fixing member 21 is mounted on the filter cup support 1, and when the filter cup support 1 is mounted on the filter position, the identification device 20 identifies the filter cup 2 or the protrusion 211. The filter position can be a suspended U-shaped locking block, and the filter cup support 1 can be detachably suspended on the U-shaped locking block of the machine body. Of course, in other embodiments, the filter position can also be a locking block of other shapes, such as two or three or more inwardly snapping locking blocks; no particular limitation is made here.

[0048] Therefore, it is understandable that the coffee machine connects the fixing part 21 to the filter cup 22, so that the fixing part 21 and the filter cup 22 cooperate to form a filter cup part 2 as a whole. Each filter cup part 2 corresponds to a different height, or each fixing part 21 has a protrusion 211 at a different position from other fixing parts 21 that can indicate the type of filter cup. When the filter cup 22 is mounted on the filter cup holder 1 and the filter cup holder 1 is mounted on the filter position of the machine body, the identification device 20 on the machine body can identify the type of filter cup 22 by identifying the height of the filter cup part 2 or the position of the protrusion 211 on the fixing part 21. The machine body prepares the corresponding type of beverage based on the type of filter cup 22, effectively avoiding errors. Moreover, since the filter cup 22 is fixed to the filter cup holder 1 by the fixing part 21, only one filter cup holder 1 is needed to accommodate different types of filter cup parts 2, eliminating the need for multiple filter cup holders 1, which can greatly reduce costs and the types and number of equipment components.

[0049] In addition, it should be noted that, as Figure 11 As shown, the filter cup 2 and the identification device 20 are also linked to a safety circuit. Specifically, the filter cup 2 acts as a mechanical trigger, linking an electrical safety circuit to prevent the machine from starting in a dangerous situation. Understandably, when the filter cup 2 is not mounted on the filter cup holder 1, and the filter cup holder 1 is directly mounted on the filter position of the coffee machine, there is a risk that there may be moving parts (such as the electric tamping head 30) or high-energy electrical components (such as plasma components that generate high temperature, high pressure, or electric arcs) directly above the filter cup holder 1. Since the bottom of the filter cup holder 1 does not have a structure to prevent fingers from entering, if a user's fingers are inserted from the bottom, they will be directly exposed to the moving parts or high-energy components, causing serious injury. Therefore, by using the filter cup 2 as a mechanical trigger, when the filter cup 2 is assembled on the filter cup holder 1 and then the filter cup holder 1 is directly installed on the filter position of the coffee machine, the safety circuit of the coffee machine is activated when the identification device 20 senses the filter cup 2 or the protrusion 211, and the machine is allowed to start. If there is any missing or improper placement, the electrical safety circuit will be disconnected, physically preventing the energy supply of dangerous components and fundamentally eliminating the possibility of starting dangerous actions in the exposed area of ​​the fingers.

[0053] Each of the filter cups 2 corresponds to a different height;

[0054] When filter cups 2 of different heights are loaded into the filter position of the machine body, the protrusions 211 on the filter cups 2 can abut against the trigger rod 201 and drive the trigger rod 201 to move, so that the trigger rod 201 moves to contact the identification switch 202 that is adapted to the height of the filter cups 2, thereby identifying the type of filter cup 22 and accurately selecting the corresponding beverage type for preparation.

[0058] When the fixing member 21 is mounted on the filter cup holder 1 and the filter cup holder 1 is mounted on the filter position, the protrusion 211 abuts against the corresponding position of the trigger rod 201 and drives the trigger rod 201 to move, so that the trigger rod 201 moves to contact the identification switch 202. The identification switch 202 identifies the specific position of the protrusion 211, thereby distinguishing the filter cup 22. The coffee machine selects the corresponding beverage type for preparation based on the identified filter cup 22 type.
