Description

Technical Field

[0001] This utility model relates to a coffee machine accessory, specifically a detachable and washable brewing structure for a fully automatic coffee machine. Background Technology

[0002] The brewing components of fully automatic coffee machines are in constant contact with coffee grounds and steam, requiring frequent disassembly and cleaning to prevent bacterial growth. However, the structural design of the brewing components in existing technologies has the following key flaws:

[0003] 1. Forced coupling between the power mechanism and extraction components complicates maintenance: Existing brewing components often integrate the power transmission mechanism (piston drive rod, gear set) with the extraction components (brewing cup, sealing ring) into a single structure. When cleaning, the power mechanism and extraction mechanism must be completely disassembled. Since the power mechanism contains precision components requiring regular lubrication, such as piston guides and drive rod hinges, the lubricant is easily washed away by water during cleaning. Before reinstallation, users must replenish the lubrication points with specialized grease, requiring a high level of expertise. Ordinary users are highly susceptible to insufficient lubrication, leading to component wear or grease contamination of the extraction channel.

[0004] 2. Risk of structural damage from repeated disassembly and assembly: Traditional brewing components use multiple screws for fixing or nested snap-fit ​​connections, requiring significant mechanical force to be applied to the locking mechanism each time they are disassembled. Frequent disassembly and assembly can easily lead to stripped threads and fatigue of the snap-fit ​​mechanism, especially at the contact area between the locking tongue and the locking hole, thus reducing locking reliability. More seriously, repeated insertion and removal of the power mechanism and docking seat will accelerate the wear of the connection port between the drive rod and the power arm, causing pressure fluctuations during coffee extraction and directly affecting the consistency of coffee quality.

[0005] 3. Inconvenient User Operation: Mainstream products require users to disconnect the drive rod from the power arm before disassembly, usually by rotating it to a specific angle or pressing a hidden clip, and then operating the external locking button. This step-by-step operation lacks clear physical feedback, and users often forcibly pull the component without fully disconnecting the drive connection, resulting in drive rod deformation or even power overload damage. Therefore, further improvements are necessary. Utility Model Content

[0013] Furthermore, a locking post is provided in the accommodating area, and correspondingly, a locking hole is provided on the brewing component. When the brewing component is installed, the locking post is inserted into the locking hole and mates with it.

[0014] Furthermore, the brewing components include a brewing cup and a brewing stand fixedly installed on one side thereon, and the brewing stand is also provided with a handle.

[0015] Furthermore: a piston is slidably installed inside the brewing cup, and several extraction holes are opened through the piston. A drive rod extends downward from the bottom of the piston and is connected to a power arm set in the docking seat.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings. A detachable brewing structure for a fully automatic coffee machine includes a main body 1, a docking seat 2 is provided inside the main body 1, and a disassembly cavity 3 is provided on the main body 1 corresponding to the position of the docking seat 2. The brewing component 4 is detachably installed in the main body 1 through the disassembly cavity 3 and docks with the docking seat 2.

[0034] The brewing component 4 is provided with a locking mechanism, which engages with the docking seat 2 to lock the relative position between the brewing component 4 and the docking seat 2.

[0035] In one embodiment: the docking seat 2 is fixedly installed inside the main body 1, and a receiving area 21 is provided on one side for docking with the brewing component 4, and the brewing component 4 is installed in the receiving area 21.

[0036] In one embodiment: the receiving area 21 is a concave arc groove, and a docking platform 22 extends from the bottom of the arc groove inward. Correspondingly, the brewing component 4 is provided with an arc cylindrical surface 41 that cooperates with the receiving area 21. The arc cylindrical surface 41 is embedded in the arc groove, and a receiving platform 42 is provided at the bottom of the arc cylindrical surface 41, which covers the docking platform 22.

[0037] In one embodiment: the containing area 21 is provided with a liquid outlet 23, and correspondingly, the brewing component 4 is provided with a connecting pipe 43. When the brewing component 4 is installed, the connecting pipe 43 is inserted into the liquid outlet 23 and connected to it.

[0038] In one embodiment: the connecting pipe 43 is fitted with a sealing ring 44, which seals the gap between the connecting pipe 43 and the liquid outlet 23.

[0039] In one embodiment: a locking post 24 is provided in the accommodating area 21, and correspondingly, a locking hole 45 is provided on the brewing component 4. When the brewing component 4 is installed, the locking post 24 is inserted into the locking hole 45 and docks with it.

[0040] In one embodiment: the brewing component 4 includes a brewing cup 46 and a brewing stand 47 fixedly installed on one side thereon, and the brewing stand 47 is also provided with a handle 48.

[0041] In one embodiment: a piston 461 is slidably installed inside the brewing cup 46, and a plurality of extraction holes 462 are opened through the piston 461. A drive rod 463 extends downward from the bottom of the piston 461 and is connected to a power arm 25 disposed in the docking seat 2. The power arm 25 pushes the piston 461 to move inside the brewing cup 46 through the drive rod 463.

[0042] In one embodiment: the locking mechanism includes locking arms 5 hinged to both sides of the brewing component 4, one end of the locking arm 5 is provided with a locking tongue 51, the locking tongue 51 passes through the locking groove 49 located on the brewing component 4 and is connected to the locking hole 26 provided on the docking seat 2.

[0043] The locking mechanism also includes a button 6 that is slidably mounted on the brewing component 4. The other end of the locking arm 5 extends into the movement trajectory of the button 6. The button 6 pushes the locking arm 5 to move, thereby connecting or separating the locking tongue 51 from the locking hole 26.

[0044] In one embodiment: a locking spring 7 is provided between the locking arm 5 and the brewing component 4, and the locking spring 7 pushes the locking tongue 51 to move towards the locking hole 26 through the locking arm 5; a return spring 8 is provided between the button 6 and the brewing component 4, and the return spring 8 pushes the button 6 to bounce outward.

[0045] Working Principle: The core of this fully automatic coffee machine's detachable and washable brewing structure lies in its detachable design, which enables the installation of brewing components, coffee extraction, and disassembly for cleaning. Its working principle specifically involves the following steps:

[0046] 1. Installation of brewing components:

[0047] The user inserts the brewing component 4 into the main body 1 through the disassembly cavity 3. The arc-shaped cylindrical surface 41 on the brewing component 4 mates with the arc-shaped groove in the receiving area 21 on the docking seat 2. The arc-shaped cylindrical surface 41 is embedded in the arc-shaped groove, which serves as a guide to ensure that the brewing component 4 can slide smoothly into the correct position.

[0048] During the sliding process, the receiving platform 42 on the brewing component 4 covers the docking platform 22 on the docking seat 2, forming a stable support structure.

[0049] Simultaneously, the connecting pipe 43 on the brewing component 4 is inserted into the liquid outlet 23 on the docking seat 2, thus connecting the coffee liquid outflow channels. The sealing ring 44 fitted onto the outside of the connecting pipe 43 fills the gap between the connecting pipe 43 and the liquid outlet 23 to prevent liquid leakage.

[0050] In addition, the locking hole 45 on the brewing component 4 is aligned with the locking pin 24 on the docking seat 2. The locking pin 24 is inserted into the locking hole 45 to further fix the position of the brewing component 4 and prevent it from shifting during use.

[0051] When the brewing component 4 is fully slid into the receiving area 21, the locking arm 5 in the locking mechanism, pushed by the locking spring 7, causes the locking tongue 51 to pass through the locking groove 49 on the brewing component 4 and insert into the locking hole 26 on the docking seat 2, automatically locking the relative position of the brewing component 4 and the docking seat 2. The locking tongue is provided with a guide ramp. When the brewing component is installed, the mutual compression between the guide ramp and the outer wall of the locking hole causes the locking tongue to retract. Once the docking is in place, the locking tongue can automatically pop out and insert into the locking hole, achieving automatic locking.

[0052] 2. Coffee extraction process:

[0053] The brewing assembly 4 includes a brewing cup 46 and a brewing base 47 fixedly mounted on one side thereon. The brewing cup 46 contains coffee grounds and has a piston 461 that slides inside.

[0054] A number of extraction holes 462 are provided through the piston 461, and a drive rod 463 extends downward from the bottom of the piston 461. The drive rod 463 is connected to the power arm 25 in the docking seat 2.

[0055] The power arm 25 pushes the piston 461 up and down within the brewing cup 46 via the drive rod 463. The movement of the piston 461 may be used to compress coffee grounds or control the path of water flow.

[0056] Hot water enters the brewing cup 46 through the sealed piston inside the main body, comes into contact with the coffee powder, and is extracted through the extraction hole 462 on the piston 461.

[0057] The extracted coffee liquid flows into the outlet hole 23 through the connecting pipe 43, and then flows out of the coffee machine through the outlet channel in the main body 1.

[0058] 3. Disassembly of brewing components:

[0059] The user initiates the disassembly process by pressing button 6 on brewing component 4.

[0060] Specifically, the user holds the handle and presses button 6 to push the locking arm 5 to move, causing the locking tongue 51 to retract from the locking hole 26 and release the lock between the brewing component 4 and the docking seat 2.

[0061] The user pulls it out of the disassembly chamber 3 using the handle 48. During the pulling process, the connecting pipe 43 is pulled out from the liquid outlet 23, the locking pin 24 is pulled out from the locking hole 45, and the brewing component 4 is completely separated from the main body 1.

[0062] After disassembly, users can clean brewing component 4 to remove coffee grounds and residue.

[0063] When button 6 is not pressed, the reset spring 8 pushes button 6 outward to return it to its initial state, making it easier for the next operation.

[0064] Compared to traditional technologies, this removable and washable design improves hygiene and ease of maintenance.

[0065] Specifically: the brewing component 4 is detachably installed inside the main body 1 through the disassembly chamber 3, which allows the user to easily remove it for cleaning, removing coffee grounds and residues, keeping the coffee machine hygienic, extending its service life, and ensuring that the taste of the coffee is not contaminated.

[0066] Meanwhile, the fit between the arc-shaped cylindrical surface 41 and the arc-shaped groove, as well as the coverage of the receiving platform 42 and the docking platform 22, ensures that the brewing component 4 is accurately positioned during installation, preventing shaking or misalignment during use. Furthermore, the docking of the locking pin 24 and the locking hole 45 further enhances the stability of the installation, preventing accidental detachment.

[0067] During installation, the brewing component 4 automatically locks itself by sliding in through the arc-shaped groove, requiring no complicated operation. Disassembly is simple: just press button 6 to unlock. The handle 48 is designed for easy grip and operation, reducing the difficulty of use.

[0068] Meanwhile, the locking spring 7 and the return spring 8 enable the locking mechanism and button 6 to have an automatic reset function, improving the convenience and reliability of operation.

[0069] Furthermore, compared to traditional technologies, this brewing component 4, being an independent module, is easy to disassemble and install. When cleaning the equipment, only the brewing component itself needs to be disassembled, while the main body with the motor mechanism remains fixed inside the coffee machine and does not require disassembly. Therefore, this brewing component can be easily disassembled for cleaning and then directly reinstalled for use, without the need for lubrication or other procedures, significantly reducing the user's workload. Additionally, the brewing component is compact and can be rinsed directly or placed in a dishwasher for cleaning, reducing the labor costs associated with the coffee machine's long-term use. If brewing component 4 is damaged or needs replacement, the user can directly replace this module without repairing the entire coffee machine, reducing maintenance costs and thus enabling its widespread adoption.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
