Description

Technical Field

[0001] This utility model relates to the field of coffee machines, specifically to a disassembly and assembly structure for a coffee machine brewing unit. Background Technology

[0002] Currently, most coffee machine brewing units employ a detachable structure. The main purpose of this design is to facilitate regular, thorough cleaning of the brewing components, ensuring the purity of the coffee flavor and the hygiene and safety of the equipment. However, the design of the disassembly structure in most coffee machines on the market still has significant flaws. For example, the placement of the latches is often illogical, resulting in a poor user experience. Users often need to spend considerable time and effort when disassembling or installing the machines, and sometimes even become confused due to the complexity of the structure. This inconvenience greatly reduces the user experience, making the cleaning process, which should be convenient, cumbersome and inefficient, hindering quick and easy disassembly and assembly. Utility Model Content

[0003] The purpose of this invention is to provide a disassembly and assembly structure for a coffee machine brewing unit that is easy to assemble and disassemble and conforms to ergonomics. The above objectives are achieved in this way.

[0004] A disassembly and assembly structure for a coffee machine brewing unit includes a brewing unit and a base. The base has an installation cavity for accommodating the brewing unit. The brewing unit has a housing. The housing and its two side frames parallel to the installation direction of the brewing unit are respectively provided with a first grip position and a second grip position. The upper part of the housing near the disassembly direction is provided with an elastic locking device. The elastic locking device is provided with a locking pin and a pressure plate for controlling the locking pin. The operating direction of the pressure plate is consistent with the movement direction of the locking pin. When the brewing unit is installed into the installation cavity, the locking pin is inserted into the base to limit the brewing unit within the installation cavity. When the brewing unit needs to be removed, the pressure plate is pressed vertically downwards, causing the pressure plate to disengage the locking pin from the base, thus unlocking the brewing unit.

[0005] This utility model can also be improved in the following ways.

[0006] Preferably, the elastic locking device includes a pressure plate cover, the finger pressure plate is slidably disposed on the pressure plate cover, and the locking pin is limited in the cavity formed by the finger pressure plate and the pressure plate cover.

[0007] The pressure plate cover is fixedly connected to the housing, and the pressure plate cover is provided with a through hole for the locking pin to pass through, so that the locking pin can be smoothly inserted into or removed from the base under the action of the pressure plate.

[0008] Furthermore, it also includes a return spring. The bottom of the locking pin is provided with a limiting protrusion. One end of the return spring is sleeved on the lower part of the limiting protrusion, and the other end of the return spring is fixedly connected to the side of the pressure plate cover near the ground. When the locking pin is not under force, the locking pin extends upward out of the pressure plate cover, and the extension position of the locking pin is higher than the frame of the brewing unit.

[0009] When the acupressure plate is pressed vertically downwards, the acupressure plate moves the locking pin downwards. At this time, the return spring is compressed, the locking pin is dislodged from the base, and the brewing unit is unlocked. When the acupressure plate is released, the return spring, due to its own elastic restoring force, pushes the limiting protrusion upwards, which in turn moves the locking pin upwards, causing the locking pin to extend upwards again from the pressure plate cover, returning to the extended position when the locking pin is not under force, so as to limit the brewing unit in the mounting cavity again.

[0010] Furthermore, the acupressure plate is recessed inward toward the housing with a pressure groove. The outer wall of the pressure groove abuts against the limiting protrusion. When the acupressure plate slides downward, the pressure groove presses against the limiting protrusion, causing the locking pin to move downward.

[0011] The groove is approximately trapezoidal in shape, with its side curvature matching the shape of the limiting protrusion. This design ensures full contact and even force distribution between the groove and the limiting protrusion as the acupressure plate slides downwards, allowing the locking pin to move smoothly without jamming or shifting. Furthermore, the depth of the groove is carefully designed to provide sufficient pressure for the locking pin to move without compromising the overall strength and stability of the acupressure plate due to excessive depth. In addition, the smooth surface of the groove reduces friction with the limiting protrusion, further improving operational smoothness.

[0012] Preferably, the first grip position and the second grip position are at the same height, and both the first grip position and the second grip position are provided with an arc-shaped trajectory, wherein the arc radius of the first grip position is larger than the arc radius of the second grip position.

[0013] This design allows for a more natural fit to the hand's curves, enhancing comfort. The larger radius of the first grip area allows for greater pressure during operation, while the smaller radius of the second grip area is suitable for scenarios requiring more precise manipulation, meeting diverse operational needs. Furthermore, both the first and second grip areas have an anti-slip surface, effectively increasing friction with the hand and preventing slippage during operation, further improving stability and safety.

[0014] By adopting the above technical solution, this utility model, with its grip position and locking structure, allows users to naturally and comfortably place their fingers in the grip areas on both sides during disassembly and assembly. Whether using the unused index finger or the flexible middle finger, simply pressing down lightly on the acupressure plate is enough to easily complete the unlocking operation; similarly, the reverse operation is equally simple and efficient during installation. This innovative design fully conforms to ergonomic principles, taking into account the natural placement of the fingers and the habit of applying force, while optimizing the overall feel and smoothness of operation during use. This ensures that users can experience significant convenience and a high degree of control throughout the entire disassembly and assembly process, truly achieving the effect of operation at will and ease of use.

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Combination Figure 1 and Figure 2 This embodiment provides a disassembly and assembly structure for a coffee machine brewing unit, mainly including a brewing unit 2 and a base 1. The base 1 has an internal mounting cavity 11 for accommodating the brewing unit 2.

[0024] The brewing unit 2 is externally provided with a housing 3. To facilitate user grip, a first grip position 31 and a second grip position 32 are respectively provided on the two side frames of the housing 3 parallel to the installation direction of the brewing unit. In this embodiment, the first grip position 31 and the second grip position 32 are at the same height and are both designed as inwardly concave arc-shaped trajectories. Specifically, the radius of the arc of the first grip position 31 is larger than that of the second grip position 32. This differentiated design allows for a better fit between the user's hand and the grip; the first grip position 31 facilitates overall assembly and disassembly with greater force, while the second grip position 32 is suitable for precise positioning operations. To further improve the feel and safety, the surfaces of both the first grip position 31 and the second grip position 32 are treated with an anti-slip coating.

[0025] Combination Figures 3 to 4 In order to enable the brewing unit 2 to be quickly locked and unlocked on the base 1, a set of elastic locking device 4 is provided on the upper part of the housing 3 on the side closer to the disassembly direction.

[0026] Specifically, the elastic locking device 4 includes a pressure plate cover 42 fixed to the housing 3 by screws. A pressure plate 41 is slidably mounted on the pressure plate cover 42, and the operating direction of the pressure plate 41 is vertical up and down. A locking pin 43 is positioned within the cavity formed by the pressure plate 41 and the pressure plate cover 42. The pressure plate cover 42 has a through hole 45 through which the locking pin 43 passes.

[0027] The bottom of the locking pin 43 is provided with a limiting protrusion 431. One end of the return spring 44 is sleeved on the lower part of the limiting protrusion 431, and the other end is fixedly connected to the inner bottom of the pressure plate cover 42. In its natural state, the return spring 44 is in an extended or slightly compressed state, and its elastic force drives the locking pin 43 to move upward, so that its upper part passes through the through hole 45 and extends upward out of the pressure plate cover 42. At this time, the extended position of the locking pin 43 is higher than the frame of the brewing unit 2, preparing for locking.

[0028] The acupressure plate 41 is recessed inward toward the housing 3 by a pressure groove 411. The outer wall of the pressure groove 411 abuts against the limiting protrusion 431 at the bottom of the locking pin 43. The pressure groove 411 is preferably trapezoidal in shape, and its side curvature is adapted to the shape of the limiting protrusion 431 to ensure uniform force distribution and smooth transmission.

[0029] Combination Figure 5 and Figure 6Installation process: The user holds the first grip position 31 and / or the second grip position 32 with one hand, while simultaneously pressing the acupressure plate 41 vertically downwards with one finger. The acupressure plate 41 slides downwards, and the pressure groove 411 on it presses against the limiting protrusion 431 at the bottom of the locking pin 43, causing the entire locking pin 43 to move downwards against the elastic force of the return spring 44. The brewing unit 2 is pushed into the mounting cavity 11 of the base 1 along the installation direction. When it reaches the correct position, the acupressure plate 41 is released. Under the elastic force of the return spring 44, the locking pin 43 will automatically spring up and insert into the preset locking hole on the base 1, thereby reliably limiting the brewing unit 2 in the mounting cavity 11, completing the installation.

[0030] Combination Figure 5 and Figure 6 Disassembly process: When it is necessary to remove the brewing unit 2, the user holds the first grip position 31 and / or the second grip position 32 with one hand, while simultaneously pressing the acupressure plate 41 vertically downward with one finger. The acupressure plate 41 slides downward, and the pressure groove 411 on it presses against the limiting protrusion 431 at the bottom of the locking pin 43, causing the entire locking pin 43 to move downward against the elastic force of the return spring 44. When the top of the locking pin 43 is completely disengaged from the locking hole of the base 1, the brewing unit 2 is unlocked. At this time, the user can then use the grip positions to smoothly pull the brewing unit 2 out of the mounting cavity 11, completing the disassembly.

[0031] In summary, this utility model, through its ergonomically designed grip position on the housing and its downward-pressing unlocking mechanism aligned with the direction of movement of the locking pin, allows the entire assembly and disassembly process to be easily completed with one hand. The operation is simple, effortless, and intuitive, greatly enhancing the user experience.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
