Description

Technical Field

[0001] This utility model relates to the technical field of coffee machines, and more particularly to a funnel and a coffee machine having the same. Background Technology

[0002] Currently, there are espresso machines on the market. Espresso machines work by rapidly passing a mixture of high-pressure steam and water through ground coffee powder to extract the coffee instantly. Espresso machines typically include a funnel structure with a handle.

[0003] Chinese utility model patent CN222888862U discloses a funnel structure, including a handle, a funnel, and a filter cup assembly. One end of the handle is fixedly connected to the funnel, and a first inner cavity is formed inside the funnel. The filter cup assembly is detachably installed in the first inner cavity. A spray hole is provided at the bottom of the filter cup assembly. A protrusion is provided on the bottom plate of the first inner cavity, and a milk foaming plate is provided on the protrusion, with the milk foaming plate corresponding to the spray hole. This configuration, with the protrusion on the bottom plate of the first inner cavity and the milk foaming plate on the protrusion, allows coffee to spray out from the spray hole of the filter cup assembly. The coffee sprays onto the milk foaming plate, and the impact generates more foam, thus achieving the function of frothing the coffee.

[0004] However, during the use of a coffee machine, the high temperature and pressure of hot water impacts the coffee grounds inside the funnel, causing them to form a solid coffee puck. After extraction, the coffee puck needs to be emptied from the funnel for cleaning. However, after being impacted by water pressure, the coffee puck adheres to the inner wall of the funnel, requiring considerable vibration to remove it, making cleaning inconvenient. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, the present invention provides a funnel and a coffee machine having the same.

[0006] The above-mentioned problems of this utility model are solved by the following technical solution: A funnel, comprising, A funnel holder with a handle, wherein a cavity is formed inside the funnel holder, and the upper opening of the funnel holder communicates with the cavity to form a cup groove, and a liquid outlet hole is provided at the bottom of the cup groove; A filter cup is located in the cup groove, and the bottom of the filter cup has a liquid outlet to discharge liquid into the cup groove; A filter screen is movably disposed inside the filter cup, and a drive structure capable of supporting the filter screen is disposed inside the cup groove. The drive structure includes a drive component and a control component that drives the drive component to move. After coffee extraction is completed, the user operates the control component to drive the filter screen upward through the drive component, thereby loosening the coffee powder cake adhering to the bottom of the filter cup.

[0007] By adopting the above technical solution, during the movement of the filter, the outer edge of the powder cake and the inner wall of the filter cup generate relative friction, which breaks the tightness of the outer periphery of the powder cake, realizing "one-click loosening + easy pouring", simplifying the cleaning steps and improving the user experience.

[0008] A further configuration of the above technical solution is as follows: the driving component is a push button, which is movably arranged along the length direction of the handle; the driving component is a push block, which is provided with a pushing surface capable of vertically pushing the filter screen.

[0009] A further feature of the above technical solution is that the pushing surface is an inclined surface.

[0010] A further provision of the above technical solution is that the filter screen includes a filter frame and a screen plate mounted on the filter frame, the bottom of the filter frame extends toward the funnel seat with a drive column, and the bottom of the funnel seat is provided with a clearance hole that allows the drive column to move. The drive column is located above the push surface.

[0011] A further feature of the above technical solution is that the lower end face of the drive column is an arc-shaped surface.

[0012] By adopting the above technical solution, the inclined pushing surface of the drive component cooperates with the drive column at the bottom of the filter screen to convert the user's horizontal pushing force on the push button into the vertical upward movement of the filter screen. The mechanical conversion is efficient and the operation is labor-saving. The lower end face of the drive column is set as an arc surface to reduce the frictional resistance with the pushing surface and improve the smoothness of movement.

[0013] A further provision of the above technical solution is that the push block is also provided with a reset member, which exerts a horizontal pressure on the push block, driving the push block to move towards the handle side.

[0014] By adopting the above technical solution, the pusher is equipped with a reset component, which can automatically reset after the external force is removed, ensuring that the filter screen returns to its initial position for easy use next time. The structure is compact and reliable.

[0015] A further provision of the above technical solution is that the filter screen includes a filter frame and a mesh plate embedded in the filter frame; the filter frame is provided with a groove that cooperates with the mesh plate, and a support column extends from the bottom of the groove, the support column supports the mesh plate, so that a filter cavity is formed between the mesh plate and the groove.

[0016] By adopting the above technical solution, the filter screen forms a filter cavity through the support column, so that the coffee liquid flows into the filter cavity in a concentrated manner after being filtered by the screen plate, and then flows out in an orderly manner through the leakage hole, avoiding uneven distribution of the extract and ensuring stable coffee extraction effect.

[0017] This utility model also discloses a coffee machine, including the funnel described above, and a main unit; the main unit is provided with a funnel installation interface below the drain outlet so that the funnel can be positioned and installed below the drain outlet; The funnel mounting interface includes guide grooves formed on both sides below the lower opening, and the funnel is provided with guide edges that cooperate with the guide grooves.

[0018] A further provision of the above technical solution is that an elastic element is provided in the guide groove, and the elastic element extends into the guide groove through an elastic groove on the guide groove; The funnel is provided with a positioning groove that mates with the elastic element.

[0019] A further provision of the above technical solution is that: a mounting bracket is provided on the main unit below the drain outlet, and the guide groove and elastic element are provided on the mounting bracket.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an active filter screen and a matching drive structure inside the filter cup, users can drive the filter screen upward by operating the control unit after coffee extraction, which loosens the coffee cake adhering to the bottom of the filter cup. The coffee cake can be easily poured out without vibrating or disassembling it, solving the problem of difficult cleaning caused by the coffee cake sticking tightly to the inner wall due to water pressure impact in traditional funnels. The guide groove of the coffee machine main unit cooperates with the guide edge of the funnel, combined with the locking structure of the elastic element, so that the funnel can be accurately positioned and firmly fixed after installation, preventing the funnel from falling off due to vibration or accidental contact during use, thus improving the safety of equipment use.

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] like Figure 1-9 As shown in the following embodiment, a funnel and a coffee machine having the same are provided.

[0033] Example 1 A funnel 4, comprising, A funnel 4 seat 100 with a handle 110 has a cavity formed inside the funnel 4 seat 100. The upper opening of the funnel 4 seat 100 communicates with the cavity to form a cup groove 101. A liquid outlet hole 102 is provided at the bottom of the cup groove 101. The filter cup 200 is located in the cup groove 101, and the bottom of the filter cup 200 has a liquid outlet to discharge liquid into the cup groove 101; A filter screen 300 is movably disposed inside the filter cup 200, and a drive structure capable of supporting the filter screen 300 is disposed inside the cup groove 101. The drive structure includes a drive component and a control component that drives the drive component to move. After coffee extraction is completed, the user operates the control component to drive the filter screen 300 upward through the drive component, thereby loosening the coffee powder cake adhering to the bottom of the filter cup 200.

[0034] The above is the basic scheme of this embodiment.

[0035] Specific reference Figure 1 and Figure 2 As shown, the main structure of the funnel base 100 adopts a cup-shaped structure, with a large-diameter opening at the top, extending downwards to form a cup groove 101 of suitable depth. This cup groove 101 matches the shape of the filter cup 200, allowing it to be securely placed inside. At the bottom of the funnel base 100, a liquid outlet 102 is provided for the final outflow of coffee liquid. The filter cup 200 is completely embedded inside the cup groove 101, tightly integrated with the funnel base 100 to form a stable overall device.

[0036] Inside the filter cup 200, near the bottom, there is a movable filter screen 300 that can move up and down. The filter screen 300 is made of food-grade stainless steel, and the mesh diameter ensures the best filtration effect.

[0037] In practical use, the ground coffee powder is first evenly poured into the filter cup 200, where it naturally accumulates on the surface of the filter screen 300 under gravity. A professional tamper is then used to apply appropriate pressure to the coffee powder, forming a moderately compacted coffee puck within the filter cup 200. When extraction begins, high-temperature, high-pressure hot water from the coffee machine is injected into the filter cup 200 through the top inlet, fully saturating the coffee puck and completing the extraction process. The extracted coffee liquid passes sequentially through the fine mesh of the filter screen 300 and the outlet hole 102 at the bottom of the funnel 4 base 100, ultimately flowing into a pre-placed container.

[0038] After the extraction process is complete, the entire funnel 4 device must be removed from the coffee machine. At this point, the operator can operate the control unit, which, through mechanical linkage, drives the internal drive component to generate thrust. During this movement, the drive component pushes the filter 300 upwards along its central axis, simultaneously displacing the coffee pouch attached to its surface. During this process, the outer edge of the coffee pouch experiences relative friction with the inner wall of the filter cup 200. This relative movement effectively breaks down the structural compactness of the coffee pouch, causing it to separate from the inner wall of the filter cup 200. Finally, the user simply needs to grip the handle 110 on the funnel 4 holder 100 and rotate the entire device 180 degrees to easily dispose of the completely loosened coffee pouch.

[0039] It should be noted that in the actual operation of this embodiment, the user can also choose to first flip the funnel 4 device, and then operate the control component to push the filter 300 after the device is inverted. This method can also effectively push the powder cake out of the filter cup 200 completely. This flexible operation sequence design makes the cleaning process more user-friendly and convenient.

[0040] Specifically, in this embodiment, the driving component is a push button 500, which is movably arranged along the length direction of the handle 110; the driving component is a push block 400, which is provided with a pushing surface 401 that can push the filter screen 300 vertically.

[0041] Specific reference Figure 2 and Figure 3 As shown, the push button 500 is mounted on the handle 110, located near the funnel seat 100. Inside the handle 110, there is a movable groove 111 that accommodates the reciprocating movement of the push button 500. This groove 111 provides smooth movement space and trajectory for the push button 500. A portion of the push button 500 protrudes from the surface of the handle 110, allowing the user to operate it with their fingers. External force is applied to displace the push button 500 within the movable groove 111.

[0042] When the user grips the handle 110, their thumb or forefinger can naturally contact the exposed push button 500. At this point, the user only needs to apply appropriate force to make the push button 500 slide smoothly towards the side of the funnel 4 seat 100 along the guide direction of the movable groove 111. The movement of the push button 500 causes the connected push block 400 to move synchronously. This linkage design ensures that the pushing surface 401 on the push block 400 can accurately follow the movement trajectory of the push button 500. During the movement, the pushing surface 401 will make direct contact with the filter screen 300 structure. Through this contact, the pushing surface 401 can apply a vertically upward force to the filter screen 300, thereby effectively lifting the filter screen 300 upward to complete the expected operation function. The entire transmission process is reasonably designed, easy to operate, and achieves a smooth human-machine interaction experience.

[0043] Preferably, in this embodiment, the push button 500 and the push block 400 are connected in a limiting manner.

[0044] Specific reference Figure 3 and Figure 4 As shown, a connecting groove 402 is provided on the push block 400 facing the push button 500. The front end of the push button 500 is provided with a protrusion 511 that cooperates with the limiting groove 512. The protrusion 511 is embedded in the limiting groove 512, so that the push button 500 and the push block 400 form an integral structure.

[0045] Alternatively, the push button 500 can be configured as an integral structure, or the part that enters the handle 110 and the operating part can be configured separately. In this embodiment, the push button 500 is configured as a split structure consisting of a toggle part 520 and a push part 510. The toggle part 520 is provided with a limiting post 521, and the push part 510 is provided with a limiting groove 512 that cooperates with it.

[0046] Preferably, in this embodiment, the pushing surface 401 is an inclined surface.

[0047] Based on the above configuration, the pushing surface 401 is designed as an inclined surface with a certain angle, its main function being to realize the conversion and adjustment of the driving direction. Through this special inclined surface structure, the pushing force applied by the operator to the push button 500 in the horizontal direction, as well as the displacement of the push button 500, can be effectively converted into the vertical movement of the filter screen 300. This mechanical conversion mechanism not only achieves a 90-degree change in the direction of motion but also ensures efficient force transmission, enabling precise control of the lifting and lowering movement of the filter screen 300 by the horizontal pushing action. This design cleverly utilizes the mechanical properties of an inclined surface, converting linear motion in one direction into linear motion in another, thus realizing the conversion of motion form and the transmission of force.

[0048] To ensure the driving of the filter screen 300 by the pushing surface 401, in this embodiment, the filter screen 300 includes a filter frame 310 and a mesh plate 320 mounted on the filter frame 310. The bottom of the filter frame 310 extends towards the funnel 4 seat 100 with a driving column 311. The bottom of the filter cup 200 is provided with a clearance hole that allows the driving column 311 to move. The drive column 311 is located above the push surface 401.

[0049] Specific reference Figure 2 As shown, in this embodiment, the filter screen 300 is installed horizontally within the internal cavity of the filter cup 200. To achieve effective drive control of the filter screen 300, a drive post 311 is integrally formed at the bottom of the filter screen 300. This drive post 311 extends vertically downwards and passes through a clearance hole at the bottom of the filter cup 200, ultimately contacting and engaging with the pushing surface 401 of the external drive device. The diameter of the clearance hole is slightly larger than the outer diameter of the drive post 311, ensuring that the drive post 311 can move freely up and down along its axial direction within the clearance hole without obstruction. This structural design ensures both effective transmission of driving force and the smoothness and reliability of the filter screen 300's movement.

[0050] To ensure that the driving surface 401 effectively drives the driving column 311, preferably, the lower end surface of the driving column 311 is set as an arc-shaped surface.

[0051] When the pushing surface 401 is displaced by the externally applied push button 500, a force is generated at the contact surface between the pushing surface 401 and the drive column 311. This force is always perpendicular to the arc-shaped surface on the drive column 311 and points towards the geometric center of the arc-shaped surface. Due to the special geometry of the arc-shaped surface, this thrust can be decomposed into two components: the vertical component exerts an upward driving force on the drive column 311, causing it to move upwards in the vertical direction. Simultaneously, the clearance hole structure within the mechanism effectively constrains the radial movement of the drive column 311, ensuring that it can only move linearly in the vertical direction without any radial offset. Through this ingenious design, precise control of the filter screen 300's trajectory is achieved, allowing it to move only vertically without any horizontal displacement or deflection.

[0052] After the pushing force on the push button 500 is removed, the push block 400 needs to be reset so that the filter screen 300 can move downward and reset under its own gravity. In this embodiment, the push block 400 is also provided with a reset member 1. The reset member 1 provides horizontal support to the push block 400, driving the push block 400 to move towards the handle 110.

[0053] Specifically, in this embodiment, the reset component 1 is a reset spring. A reset plate 120 extends from the bottom of the funnel 4 seat 100 toward the cup groove 101. The reset plate 120 has a vertical plate structure, and its extension direction is consistent with the axial direction of the funnel 4 seat 100. A reset spring is installed between the reset plate 120 and the push block 400. One end of the reset spring abuts against the end face of the reset plate 120, and the other end abuts against the inner end face of the push block 400. With this structural arrangement, the reset spring is always in a compressed state, thereby generating a continuous elastic restoring force, so that the push block 400 is always subjected to a pushing force in a direction away from the reset plate 120, maintaining a tendency to move outward. This design ensures that the push block 400 can automatically reset after completing one pushing action, preparing for the next pushing.

[0054] In this embodiment, please refer to the specific details. Figure 5 As shown, the specific implementation of the filter screen 300 is configured as follows: the filter screen 300 includes a filter frame 310 and a mesh plate 320 embedded in the filter frame 310; the filter frame 310 is provided with a groove 601 that cooperates with the mesh plate 320, and a support column 312 extends from the bottom of the groove 601. The support column 312 supports the mesh plate 320, so that a filter cavity a is formed between the mesh plate 320 and the groove 601.

[0055] During coffee extraction, the coffee puck is first evenly spread on the mesh plate 320. When hot, high-temperature, high-pressure water acts on the coffee puck in liquid form, water molecules fully saturate the coffee particles, extracting the coffee liquid. The fully extracted coffee liquid, under the influence of gravity, gradually permeates through the fine mesh of the mesh plate 320. The design of these mesh openings ensures the smooth passage of the extract while effectively blocking the passage of coffee particles. The permeated coffee liquid collects in the lower filter chamber a, which serves as a transition space to temporarily store the extract. Finally, the drain hole 313 at the bottom of filter chamber a acts as an outlet, allowing the collected coffee liquid to flow out in an orderly manner. The advantage of this structural design is that it can concentrate the extracted liquid, which is distributed over a large area, into filter chamber a. Through the guiding effect of filter chamber a, the coffee liquid ultimately flows out through the drain hole 313, thus ensuring the stability and consistency of the extraction process.

[0056] In addition, in this embodiment, a retainer 2 is provided at the bottom of the filter frame 310. The retainer 2 pulls the filter screen 300 downward, so that the filter screen 300 is always kept at the bottom of the filter cup 200 without external force.

[0057] The retainer 2 is a spring, and the bottom of the filter frame 310 has a spring post that limits the spring.

[0058] Example 2 This embodiment discloses a coffee machine, including the funnel 4 described in embodiment 1, and also including a main unit 3. Furthermore, the main unit 3 is provided with a funnel 4 installation interface below the drain outlet, so that the funnel 4 can be positioned and installed below the drain outlet. The funnel 4 has an installation interface including guide grooves 3.2 formed on both sides below the lower opening, and the funnel 4 has guide edges 4.1 that cooperate with the guide grooves 3.2.

[0059] Specific reference Figure 6 and Figure 7 As shown, in this embodiment, the guide groove 3.2 is located directly below the drain outlet of the main unit 3, and two guide groove 3.2 units are arranged symmetrically. A specific interval is reserved between these two parallel guide grooves 3.2 to form the funnel 4 installation interface. The water outlet end of the main unit 3 drain outlet is located directly above the funnel 4 installation interface area, ensuring accurate water flow.

[0060] In the specific implementation process, as a preferred option, this embodiment specifically designs the guide groove 3.2 to be horizontal. This horizontal guiding structure facilitates the stable installation and precise positioning of the funnel 4 component, while also effectively avoiding potential misalignment or jamming problems during installation. The horizontally arranged guide groove 3.2 also simplifies the installation operation process, improves assembly efficiency, and ensures the reliability and sealing of the entire drainage system connection.

[0061] In this embodiment, when the funnel 4 is installed into the funnel 4 installation interface, a positioning structure is designed to precisely position and fix it, ensuring that the installation position of the funnel 4 is completely aligned with the equipment drain outlet. This precise design not only ensures the stability of the funnel 4 installation but also effectively prevents problems such as liquid leakage or poor diversion caused by positional deviation, thereby ensuring the accuracy and reliability of the entire liquid transfer process.

[0062] The specific implementation method is as follows: an elastic element 5 is provided in the guide groove 3.2, and the elastic element 5 extends into the guide groove 3.2 through the elastic groove 611 on the guide groove 3.2; The funnel 4 is provided with a positioning groove 4.11 that cooperates with the elastic element 5.

[0063] Specific reference Figure 8 As shown, the elastic element 5 is installed inside the main unit 3. Its elastic portion extends outward through the elastic groove 611 opened on the wall of the guide groove 3.2, eventually entering the guide groove 3.2. When the operator installs the funnel 4 along the trajectory direction of the guide groove 3.2, the guide edge 4.1 on the side of the funnel 4 will contact the extended portion of the elastic element and apply a continuous squeezing force to it. This squeezing force forces the elastic portion of the elastic element 5 to contract inward and retract into the space inside the main unit 3 through the elastic groove 611. As the funnel 4 continues to advance to the predetermined installation position, the positioning groove 4.11 on the funnel 4 will be precisely aligned with the elastic groove 611 on the main unit 3. In this aligned state, the elastic element is no longer subjected to any external pressure, and its elastic portion naturally extends outward under the action of its own restoring force, re-extending from the elastic groove 611 and accurately embedding into the positioning groove 4.11 of the funnel 4. A reliable mechanical interlocking structure is formed, and the positioning and locking functions between the funnel 4 and the main unit 3 are realized through the elastic deformation and reset characteristics of the elastic element 5. Under normal working conditions, if no additional external force is applied to overcome the locking force of the elastic element, the funnel 4 assembly will always maintain a stable installation state and will not accidentally loosen or fall off from the guide groove 3.2.

[0064] Preferably, in this embodiment, the elastic element 5 is a metal torsion spring.

[0065] One end of the metal torsion spring is fixed, while the other end can deform under external force and return to its original position after the external force is removed.

[0066] Specifically, a mounting bracket 600 is provided on the main unit 3 below the drain outlet, and the guide groove 3.2 and the elastic element 5 are provided on the mounting bracket 600.

[0067] Reference Figure 9 As shown, the mounting bracket 600 adopts a horizontally placed U-shaped structure design, with its open end fully accommodating the funnel 4 for easy insertion. A protruding support shoulder 610 is formed on the inner side of this U-shaped structure. This support shoulder 610 cooperates with the lower end face of the main unit 3 at the drain outlet to form a guide groove 3.2. Of particular note is the hollow internal structure design of the mounting bracket 600. This design not only reduces the overall weight but also provides ample space for the installation of internal components.

[0068] The elastic groove 611 is located on the upper surface of the support shoulder 610, while the elastic element 5 is installed in the internal cavity of the mounting bracket 600. This arrangement allows the elastic portion of the elastic element 5 to extend outward through the elastic groove 611, protruding appropriately above the support shoulder 610, thereby achieving the intended elastic function.

[0069] In addition, in this embodiment, part of the elastic member 5 is located outside the mounting bracket 600 and is embedded in the groove 601 on the outer end face of the mounting bracket 600 to achieve fixation with the mounting bracket 600.

[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
