Description

Technical Field

[0001] The embodiments of this utility model relate to the field of coffee machine technology, specifically to a modular coffee extraction structure and a coffee machine. Background Technology

[0002] Coffee is a widely popular beverage, and coffee machines are increasingly used in homes, offices, and commercial settings. The coffee extraction mechanism is the core component of a coffee machine, and its performance directly affects the quality of the coffee.

[0003] Currently, most coffee machines on the market feature an integrated design. While this design ensures the stability of the extraction process to some extent, it has revealed many drawbacks in actual use.

[0004] From a cleaning perspective, integrated coffee machines have a complex internal structure with numerous crevices, corners, and pipes. During the coffee extraction process, coffee grounds, oils, and other residues adhere to these areas. Due to structural design limitations, these residues are difficult to remove completely. For example, ordinary cleaning tools struggle to reach the inside of some tiny pipes, and the accumulated residue can breed bacteria, affecting not only the taste and quality of the coffee but also potentially posing a health risk to the user.

[0005] In terms of maintenance, if any part of the coffee machine malfunctions, its integrated design often requires disassembly and repair of the entire extraction mechanism. This not only increases the difficulty and cost of repairs but also necessitates the operation of professional technicians, causing significant inconvenience to users. Furthermore, the disassembly and installation process may damage other components, further affecting the normal use of the coffee machine. Utility Model Content

[0006] To overcome the above-mentioned defects, embodiments of this utility model provide a modular coffee extraction structure and coffee machine, which solves the technical problem that the coffee extraction structure of existing coffee machines is inconvenient to clean.

[0007] According to one aspect, at least one embodiment of the present invention provides a modular coffee extraction structure for mounting on a coffee machine body, comprising:

[0008] The mounting bracket assembly is installed on the coffee machine body, and the mounting bracket assembly has a first slot and a second slot on the side away from the coffee machine body;

[0009] The extraction module assembly includes a housing. One side of the housing has a first positioning rod and a second positioning rod. The first positioning rod can be engaged in a first slot, and the second positioning rod can be engaged in a second slot, so that the extraction module assembly can be detachably connected to the mounting bracket assembly.

[0010] For example, in a modular coffee extraction structure provided in at least one embodiment of the present invention, the mounting bracket assembly has a protrusion, and the second slot is located on the protrusion.

[0011] For example, in at least one embodiment of the present invention, a modular coffee extraction structure is provided, which further includes:

[0012] A limiting member is rotatably mounted on the second positioning rod; the limiting member has a counterweight part, which is arranged to rotate under the action of gravity, and a limiting space is formed between the counterweight part and the second positioning rod, and the protrusion is located within the limiting space after the limiting member rotates.

[0013] For example, in a modular coffee extraction structure provided by at least one embodiment of the present invention, the length of the limiting member is less than the length of the second positioning rod, and limiting protrusions are provided at both ends of the limiting member; the limiting protrusions abut against the inner wall of the outer shell to limit the displacement of the limiting member along the axial direction of the second positioning rod.

[0014] For example, in a modular coffee extraction structure provided by at least one embodiment of the present invention, one side of the counterweight has a gripping protrusion, which is arranged to grip and drive the limiting member to rotate around the second positioning rod, so that the protrusion disengages from the limiting space.

[0015] For example, in a modular coffee extraction structure provided in at least one embodiment of the present invention, the limiting member is provided with a first guide plate on the side near the mounting bracket assembly; the first guide plate is arranged such that when the second positioning rod is inserted into the second slot, the first guide plate can guide the second positioning rod to enter the second slot along the opening direction of the second slot.

[0016] For example, in a modular coffee extraction structure provided in at least one embodiment of the present invention, a second guide plate is provided on the side wall of the first slot, and the second guide plate is arranged to guide the first positioning rod to be inserted into the first slot along the opening direction of the first slot.

[0017] For example, in a modular coffee extraction structure provided by at least one embodiment of the present invention, the mounting frame assembly is an assembled structure, the mounting frame assembly includes a first side plate and a second side plate disposed opposite to each other, and a support plate connected between the two; the mounting frame assembly is arranged such that after assembly, the first slot and the second slot are located on the side of the first side plate and the second side plate closer to the extraction module assembly.

[0018] For example, in a modular coffee extraction structure provided by at least one embodiment of the present invention, the extraction module component further includes an extraction working unit, which is disposed within the outer shell and arranged to extract coffee powder.

[0019] According to another aspect, at least one embodiment of the present invention also provides a coffee machine, including a coffee machine body and a modular coffee extraction structure.

[0020] The beneficial effects of the embodiments of this utility model are as follows:

[0021] In this invention, the first and second slots on the mounting bracket assembly form a snap-fit ​​structure with the first and second positioning rods on the outer shell of the extraction module assembly. This allows for simple insertion and removal of the extraction module assembly from the mounting bracket assembly, eliminating the need for additional tools or complex disassembly and assembly operations. This greatly simplifies the process and saves users time and effort. This detachable connection method also allows users to easily remove the extraction module assembly from the coffee machine for thorough cleaning, preventing coffee residue buildup.

[0034] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] like Figures 3-5 As shown, a modular coffee extraction structure according to an embodiment of the present invention is illustrated. The modular coffee extraction structure is used for mounting on a coffee machine body and includes a mounting bracket assembly 1 and an extraction module assembly 2. The mounting bracket assembly 1 has a plate-like structure, one side of which is fixedly mounted to the coffee machine body using an existing connection method. On the side of the mounting bracket assembly 1 away from the coffee machine body, i.e., on the side facing the extraction module assembly 2, a first slot 11 and a second slot 12 are provided. Both the first slot 11 and the second slot 12 are elongated grooves extending horizontally. The first slot 11 is located in the upper region of the mounting bracket assembly 1, and the second slot 12 is located in the lower region of the mounting bracket assembly 1, with the two arranged parallel to each other vertically.

[0036] The extraction module assembly 2 includes a housing 21, which is a box-shaped structure with a receiving space for accommodating the internal extraction working unit. On one side of the housing 21, opposite to the mounting bracket assembly 1, are a first positioning rod 22 and a second positioning rod 23. Both the first positioning rod 22 and the second positioning rod 23 are horizontally extending rod-shaped structures. The first positioning rod 22 is located at the upper part of the housing 21, corresponding to the position of the first slot 11, and the second positioning rod 23 is located at the lower part of the housing 21, corresponding to the position of the second slot 12. The cross-sectional shape of the first positioning rod 22 is adapted to the cross-sectional shape of the first slot 11, allowing it to be tightly engaged within the first slot 11; the cross-sectional shape of the second positioning rod 23 is adapted to the cross-sectional shape of the second slot 12, allowing it to be tightly engaged within the second slot 12.

[0037] When the extraction module assembly 2 needs to be installed onto the mounting bracket assembly 1, align the first positioning rod 22 on the outer shell 21 with the first slot 11 of the mounting bracket assembly 1, and the second positioning rod 23 with the second slot 12. Then, push the extraction module assembly 2 horizontally so that the first positioning rod 22 is inserted into the first slot 11 and the second positioning rod 23 is inserted into the second slot 12, until the first positioning rod 22 and the second positioning rod 23 are fully engaged in the first slot 11 and the second slot 12, respectively, thereby achieving a detachable connection between the extraction module assembly 2 and the mounting bracket assembly 1. When the extraction module assembly 2 needs to be disassembled, pull the extraction module assembly 2 in the opposite horizontal direction so that the first positioning rod 22 and the second positioning rod 23 are pulled out from the corresponding first slot 11 and second slot 12, respectively, and the extraction module assembly 2 can be removed from the mounting bracket assembly 1.

[0038] The first slot 11 and the second slot 12 on the mounting bracket assembly 1 form a snap-fit ​​structure with the first positioning rod 22 and the second positioning rod 23 on the outer shell 21 of the extraction module assembly 2. This allows for easy connection and separation of the extraction module assembly 2 from the mounting bracket assembly 1 through simple insertion and removal, eliminating the need for additional tools or complex disassembly operations. This greatly simplifies the process and saves users time and effort. This detachable connection method allows users to easily remove the extraction module assembly 2 from the coffee machine body for thorough cleaning, preventing coffee residue buildup. Because the extraction module assembly 2 is easily detachable, cleaning only requires cleaning the extraction module assembly 2, improving convenience and efficiency and ensuring the quality and hygiene of the extracted coffee. Furthermore, the modular design allows the extraction module assembly 2 to exist independently of the coffee machine body, facilitating subsequent maintenance, replacement, or upgrades, thus improving the overall performance and flexibility of the coffee machine. The first slot 11 and the second positioning rod 23 form a positioning and locking mechanism at the upper part, and the second slot 12 and the second positioning rod 23 form a positioning and locking mechanism at the lower part. The two locking structures at the upper and lower parts work together to make the connection between the extraction module assembly 2 and the mounting bracket assembly 1 more stable and reliable, ensuring that the extraction module assembly 2 will not easily loosen or fall off during the operation of the coffee machine, thus ensuring the stability and reliability of the coffee extraction process.

[0039] like Figures 2-5As shown, the mounting bracket assembly 1 has a protrusion 13 on the side facing the extraction module assembly 2. The protrusion 13 is a block-shaped structure extending outward from the surface of the mounting bracket assembly 1, and the second slot 12 is formed on the upper surface of the protrusion 13. The second positioning rod 23 of the extraction module assembly 2 is a solid rod-shaped structure. The limiting member 3 is U-shaped, and its length direction is parallel to the axis of the second positioning rod 23. It is rotatably assembled with the pin on the second positioning rod 23 through the shaft holes located on both side walls, so that the limiting member 3 can rotate around the axis of the second positioning rod 23. A counterweight 31 extends from one side wall of the limiting member 3. The center of gravity of the counterweight 31 is offset from the axis of the second positioning rod 23, so it hangs down naturally under the action of gravity. When the limiting member 3 is in the initial position, the counterweight 31 drives the limiting member 3 to rotate, so that a limiting space 32 is formed between the limiting member 3 and the second positioning rod 23. The size of the limiting space 32 is adapted to the size of the protrusion 13. Once the extraction module assembly 2 is installed in place, the protrusion 13 enters the limiting space 32. At this time, the limiting member 3 remains stationary under the gravity of the counterweight 31, and abuts against the outer surface of the protrusion 13 through the inner wall of the limiting space 32, thus limiting the extraction module assembly 2.

[0040] The length of the limiting member 3 is less than the length of the second positioning rod 23. Limiting protrusions 33 are provided on both ends of its side walls. These protrusions 33 are block-shaped structures that protrude outwards from the end of the side wall. When they contact the inner wall of the outer casing 21, they prevent the limiting member 3 from moving along the axis of the second positioning rod 23, ensuring that the limiting member 3 can only rotate around the pin and will not move axially. A gripping protrusion 34 is provided on the side wall of the limiting member 3 near the counterweight 31. This gripping protrusion 34 is a strip-shaped structure distributed along the length of the limiting member 3. When the user pinches the gripping protrusion 34 with their fingers and applies a rotational force, the limiting member 3 can be driven to rotate upwards around the axis of the second positioning rod 23, changing the opening direction of the limiting space 32. The protrusion 13 disengages from the limiting space 32, thereby releasing the limiting effect on the extraction module assembly 2. A first guide plate 35 is provided on one side wall of the limiting member 3 near the mounting bracket assembly 1. The first guide plate 35 is a plate-shaped structure that extends obliquely from the front end of the side wall to both sides. When the second positioning rod 23 is inserted into the second slot 12, the inclined surface of the first guide plate 35 contacts the side of the protrusion 13, guiding the second positioning rod 23 to smoothly enter along the opening direction of the second slot 12, thus avoiding jamming.

[0041] In this part of the structure, the cooperation between the U-shaped limiting member 3 and the protrusion 13 automatically forms a limiting position under the action of gravity, achieving locking of the connection state without additional user operation, thus improving the stability after installation. The U-shaped structure provides a larger contact area for the limiting space 32, enhancing the limiting effect on the extraction module component 2; the setting of the counterweight 31 ensures that the limiting member 3 remains locked in the absence of external force, preventing the extraction module component 2 from falling off due to vibration or other factors; the limiting protrusion 33 restricts the axial displacement of the limiting member 3, ensuring the accuracy of rotational movements; the gripping protrusion 34 provides a force application point for the user, making the unlocking operation simple and controllable; the guiding function of the first guide plate 35 reduces the alignment difficulty during installation and improves the efficiency of disassembly and assembly. The cooperation of these features adds an automatic limiting function to the detachable connection, ensuring the reliability of the connection without affecting the convenience of disassembly, and solving the loosening problem that may exist in the snap-fit ​​structure of the prior art.

[0042] like Figures 2-5 As shown, second guide plates 14 are respectively provided on both sides of the first slot 11. The second guide plate 14 is a plate-shaped structure that extends inclinedly from the inner wall of the slot towards the opening direction, and its inclination angle matches the insertion direction of the first positioning rod 22. When the first positioning rod 22 is aligned with the first slot 11, the inclined surface of the second guide plate 14 contacts the end of the first positioning rod 22, guiding the first positioning rod 22 to be smoothly inserted along the axial direction of the slot, avoiding jamming caused by angular deviation.

[0043] The second guide plate 14, in conjunction with the first positioning rod 22, provides guidance to both the upper and lower positioning structures during installation. This allows users to complete the insertion operation without precise alignment, further simplifying the installation process. The guide structure reduces frictional resistance during insertion, minimizes component wear, and extends the service life of the snap-fit ​​structure. Simultaneously, it ensures that the first positioning rod 22 is fully engaged in the slot, preventing connection instability due to incomplete engagement.

[0044] like Figures 2-5 As shown, the mounting frame assembly 1 adopts a modular structure, including a first side plate 15 and a second side plate 16 arranged opposite each other, and a support plate 17 connecting the two. The first side plate 15 and the second side plate 16 are vertically arranged plate-like components, and the support plate 17 is a plate-like component horizontally connected between the two. The three are assembled into a frame structure by screws or clips. After assembly, the first side plate 15 and the second side plate 16 have a first slot 11 and a second slot 12 respectively on their surfaces facing the extraction module assembly 2. The first slot 11 and the second slot 12 are symmetrically distributed on the two side plates, together forming a positioning structure for the extraction module assembly 2.

[0045] The modular structure makes the manufacturing and maintenance of the mounting bracket assembly 1 more flexible. Each panel can be processed individually and then assembled, reducing processing difficulty and cost. The symmetrically distributed positioning slots ensure that the extraction module assembly 2 is subjected to even force during installation, avoiding tilting or deformation caused by unilateral force and improving the overall structural stability. At the same time, the modular design facilitates subsequent partial replacement or repair of the mounting bracket assembly 1 without disassembling the entire coffee machine body, improving maintenance convenience.

[0046] like Figures 2-5 As shown, an extraction unit is installed inside the outer casing 21 of the extraction module assembly 2. This extraction unit includes an extraction chamber and a driving component. The extraction chamber is a cavity structure with an inlet and an outlet, used to hold coffee powder and extract it. The driving component is connected to the extraction chamber and can drive the extraction chamber to perform operations such as pressure extraction. The extraction unit is fixed inside the outer casing 21 by screws or clips, and its inlet and outlet are aligned with corresponding openings on the outer casing 21 for connection to the piping system of the coffee machine body.

[0047] The integrated design of the extraction unit enables the extraction module component 2 to operate independently, forming a complete modular structure together with the outer casing 21 and the mounting bracket component 1. This design facilitates the disassembly and maintenance of the entire extraction module as an independent unit. When the extraction unit malfunctions, there is no need to disassemble the complex internal structure; simply replace the entire module, thus improving the maintainability of the coffee machine. Simultaneously, the outer casing 21 protects the extraction unit, ensuring its stable operation during use.

[0048] like Figures 1-2 As shown, the coffee machine includes a coffee machine body and the aforementioned modular coffee extraction structure. An installation interface is provided on the side of the coffee machine body, and the mounting bracket assembly 1 is fixed to the installation interface by bolts or clips. The extraction module assembly 2 is connected to the positioning slot of the mounting bracket assembly 1 via the upper second positioning rod 23, and its extraction working unit's pipeline interface is connected to the water supply and drainage system of the coffee machine body.

[0049] By applying a modular coffee extraction structure to the coffee machine body, its detachable connection and automatic limit functions optimize the entire cleaning and maintenance process. Users can quickly disassemble the extraction module for deep cleaning, avoiding cleaning blind spots caused by the fixed structure of traditional coffee machines and ensuring hygienic standards for coffee extraction. The modular design also facilitates upgrades and modifications to the coffee machine, allowing for the replacement of extraction module components of different specifications as needed, thus improving the product's applicability and lifespan.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
