Description

Technical Field

[0001] The invention relates to a coffee machine accessory, in particular to a detachable and washable brewing structure for a full-automatic coffee machine. Background Art

[0002] The brewing components of fully automatic coffee machines are in contact with coffee powder and water vapor for a long time and need to be frequently disassembled and cleaned to prevent bacteria from growing. However, the structural design of the brewing components in the prior art has the following key defects: 1. The forced coupling between the power mechanism and the extraction component complicates maintenance: Existing brewing components often design the power transmission mechanism such as the piston drive rod, gear set and extraction component brewing cup and sealing ring as an integrated structure. When the user cleans, the power mechanism and the extraction mechanism must be disassembled as a whole. Since the power mechanism contains precision parts that need to be lubricated regularly, such as the piston guide and the drive rod hinge point, the grease is easily washed away by water during the cleaning process. Before reinstalling, the user needs to add special grease to the lubrication points by himself. The operation requires high professionalism. Ordinary users are very likely to cause component wear or grease contamination of the extraction channel due to insufficient lubrication.

[0003] 2. Risk of structural damage caused by repeated disassembly and assembly: Traditional brewing components are fixed with multiple screws or nested snap-on connections, and each disassembly requires a large mechanical force to be applied to the locking mechanism. Frequent disassembly and assembly can easily lead to thread stripping and elastic fatigue of the snaps, especially at the contact point between the lock tongue and the lock hole, thereby reducing the reliability of the lock. What's more serious is that the repeated insertion and removal of the power mechanism and the docking seat will accelerate the wear of the connection port between the drive rod and the power arm, causing pressure fluctuations during coffee extraction, which directly affects the consistency of coffee quality.

[0004] 3. User operation is inconvenient: mainstream products require users to first release the connection between the drive rod and the power arm before disassembly, usually by rotating a specific angle or pressing a hidden buckle, and then operating the external locking button. This step-by-step operation lacks clear physical feedback, and users often forcibly pull the components without completely releasing the drive connection, causing deformation of the drive rod or even damage due to power overload. Therefore, it is necessary to make further improvements. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a detachable brewing structure for a fully automatic coffee machine that is simple in structure and easy to use, and achieves significant improvements in cleaning and maintenance efficiency and equipment life while ensuring extraction performance through modular separation design and self-locking linkage structure.

[0009] Furthermore: a liquid outlet hole is arranged in the accommodating area, and correspondingly, a docking tube is arranged on the brewing component. When the brewing component is installed, the docking tube is inserted into the liquid outlet hole and docked with it.

[0010] Furthermore, a sealing ring is sleeved on the outer surface of the butt joint pipe, and the sealing ring seals the gap between the butt joint pipe and the liquid outlet hole.

[0011] Furthermore: a lock column is arranged in the accommodating area, and correspondingly, a lock hole is arranged on the brewing component. When the brewing component is installed, the lock column is inserted into the lock hole and docked with it.

[0012] Furthermore: the brewing assembly includes a brewing cup and a brewing seat fixedly installed on one side of the brewing cup, and the brewing seat is also provided with a handle.

[0013] Furthermore: a piston is slidably installed in the brewing cup, and a plurality of extraction holes are opened through the piston. A driving rod extends downward from the bottom of the piston and is connected to a power arm arranged in the docking seat. The power arm pushes the piston to move in the brewing cup through the driving rod.

[0014] Further: the locking mechanism comprises locking arms hingedly mounted on both sides of the brewing assembly, one end of the locking arm is provided with a locking tongue, the locking tongue passes through a locking slot on the brewing assembly and is connected to a locking hole provided on the docking seat; The locking mechanism also includes a button slidably mounted on the brewing assembly, the other end of the locking arm extends into the movable track of the button, and the button pushes the locking arm to move to achieve the connection or separation of the locking tongue and the locking hole.

[0016] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0017] 2. By designing a disassembly chamber and a detachable brewing component, users can easily disassemble the brewing component for cleaning, effectively avoiding the accumulation of coffee grounds and dirt, and significantly improving the hygiene level and coffee quality of the coffee machine.

[0018] 3.

[0031] In one embodiment, the docking seat 2 is fixedly installed in the main body 1 , and a receiving area 21 for docking with the brewing component 4 is provided on one side thereof, and the brewing component 4 is installed in the receiving area 21 .

[0032] In one of the embodiments: the accommodating area 21 is an inwardly concave arc groove, and a docking platform 22 is extended from the bottom of the arc groove inwardly of the groove. Correspondingly, the brewing component 4 is provided with an arc cylinder 41 that matches the accommodating area 21, and the arc cylinder 41 is embedded in the arc groove. A receiving platform 42 is provided at the bottom of the arc cylinder 41, and the receiving platform 42 covers the docking platform 22.

[0033] In one of the embodiments: a liquid outlet hole 23 is provided in the accommodating area 21, and correspondingly, a docking tube 43 is provided on the brewing component 4. When the brewing component 4 is installed, the docking tube 43 is inserted into the liquid outlet hole 23 and docked therewith.

[0034] In one embodiment, a sealing ring 44 is sheathed on the butt joint pipe 43 , and the sealing ring 44 seals the gap between the butt joint pipe 43 and the liquid outlet 23 .

[0035] In one of the embodiments: a locking column 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 column 24 is inserted into the locking hole 45 and docked with it.

[0036] In one embodiment, the brewing assembly 4 includes a brewing cup 46 and a brewing seat 47 fixedly mounted on one side thereof, and a handle 48 is also provided on the brewing seat 47 .

[0037] In one embodiment: a piston 461 is slidably installed in the brewing cup 46, and a plurality of extraction holes 462 are opened through the piston 461. A driving rod 463 extends downward from the bottom of the piston 461 and is connected to a power arm 25 set in the docking seat 2. The power arm 25 pushes the piston 461 to move in the brewing cup 46 through the driving rod 463.

[0038] In one embodiment: the locking mechanism comprises locking arms 5 hingedly mounted on both sides of the brewing assembly 4, a locking tongue 51 is provided at one end of the locking arm 5, the locking tongue 51 passes through a locking slot 49 on the brewing assembly 4, and is connected to a locking hole 26 provided on the docking seat 2; The locking mechanism also includes a button 6 slidably mounted on the brewing assembly 4 , the other end of the locking arm 5 extends into the movable track of the button 6 , and the button 6 pushes the locking arm 5 to move, thereby achieving the connection or separation of the locking tongue 51 and the locking hole 26 .

[0039] In one of the embodiments: a locking spring 7 is arranged between the locking arm 5 and the brewing component 4, and the locking spring 7 pushes the locking tongue 51 to always move toward the locking hole 26 through the locking arm 5; a return spring 8 is arranged between the button 6 and the brewing component 4, and the return spring 8 always bounces outward by pushing the button 6.

[0040] Working principle: The core of this fully automatic coffee machine with a detachable brewing structure is to achieve the installation of brewing components, coffee extraction and disassembly and cleaning functions through a detachable design. Its working principle is specifically divided into the following steps: 1. Installation of brewing components: The user inserts the brewing assembly 4 into the main body 1 through the disassembly and assembly cavity 3 provided on the main body 1. The arc cylindrical surface 41 on the brewing assembly 4 matches with the arc groove in the accommodating area 21 on the docking seat 2, and the arc cylindrical surface 41 is embedded in the arc groove to play a guiding role, ensuring that the brewing assembly 4 can slide smoothly into the correct position.

[0041] During the sliding process, the receiving platform 42 on the brewing component 4 covers the docking platform 22 on the docking seat 2 to form a stable supporting structure.

[0042] At the same time, the butt joint pipe 43 on the brewing assembly 4 is inserted into the liquid outlet hole 23 on the docking seat 2 to achieve the butt joint of the coffee liquid outflow channel. The sealing ring 44 set outside the butt joint pipe 43 fills the gap between the butt joint pipe 43 and the liquid outlet hole 23 to prevent liquid leakage.

[0043] In addition, the locking hole 45 on the brewing component 4 is aligned with the locking column 24 on the docking seat 2, and the locking column 24 is inserted into the locking hole 45 to further fix the position of the brewing component 4 to prevent displacement during use.

[0044] When the brewing assembly 4 completely slides into the accommodating area 21, the locking arm 5 in the locking mechanism, under the push of the locking spring 7, allows the locking tongue 51 to pass through the locking groove 49 on the brewing assembly 4 and insert into the locking hole 26 on the docking seat 2, automatically locking the relative position of the brewing assembly 4 and the docking seat 2. Among them, the locking tongue is provided with a guiding inclined surface. When the brewing assembly is installed, the mutual compression between the guiding inclined surface and the outer wall of the locking hole can make the locking tongue retract. When the brewing assembly is in place, the locking tongue can automatically pop out and insert into the locking hole to achieve automatic locking.

[0045] 2. Coffee extraction process: The brewing assembly 4 comprises a brewing cup 46 and a brewing seat 47 fixedly mounted on one side thereof. The brewing cup 46 is filled with coffee powder, and a piston 461 is slidably mounted inside.

[0046] A plurality of extraction holes 462 are formed through the piston 461 . A driving rod 463 extends downward from the bottom of the piston 461 . The driving rod 463 is connected to the power arm 25 in the docking seat 2 .

[0047] The power arm 25 pushes the piston 461 to move up and down in the brewing cup 46 through the driving rod 463. The movement of the piston 461 may be used to compress the coffee powder or control the path of the water flow.

[0048] Hot water enters the brewing cup 46 through the sealed piston in the main body, contacts the coffee powder, and is extracted through the extraction hole 462 on the piston 461.

[0049] The extracted coffee liquid flows into the liquid outlet 23 through the butt joint 43 , and then flows out of the coffee machine through the liquid outlet channel in the main body 1 .

[0050] 3. Disassembly of brewing components: The user initiates the disassembly process by pressing a button 6 on the brewing assembly 4 .

[0051] Specifically, the user holds the handle and presses the button 6 to push the locking arm 5 to move, so that the locking tongue 51 withdraws from the locking hole 26 , thereby releasing the lock between the brewing assembly 4 and the docking seat 2 .

[0052] The user pulls it out of the disassembly chamber 3 through the handle 48 . During the pulling process, the butt joint pipe 43 is pulled out from the liquid outlet 23 , the locking column 24 is pulled out from the locking hole 45 , and the brewing assembly 4 is completely separated from the main body 1 .

[0053] After disassembly, the user can clean the brewing assembly 4 to remove coffee grounds and residues.

[0054] When the button 6 is not pressed, the return spring 8 pushes the button 6 to bounce outwards, restoring the initial state to facilitate the next operation.

[0055] Compared with traditional technology, this detachable and washable design improves hygiene and maintenance convenience.

[0056] Specifically: the brewing component 4 is detachably installed in the main body 1 through the disassembly chamber 3, and the user can easily take it out for cleaning, remove coffee grounds and residues, maintain the hygiene of the coffee machine, extend its service life, and ensure that the taste of the coffee is not contaminated.

[0057] At the same time, the cooperation between the arc cylindrical surface 41 and the arc groove, as well as the covering between the receiving platform 42 and the docking platform 22, ensures that the brewing assembly 4 is accurately positioned during installation to avoid shaking or misalignment during use. The docking between the locking column 24 and the locking hole 45 further enhances the stability of the installation and prevents accidental falling off.

[0058] When installing, the brewing assembly 4 can be automatically locked by sliding into the arc groove, without complicated operation. When disassembling, it can be unlocked by pressing the button 6, and the handle 48 is designed to facilitate the user to hold and operate, reducing the difficulty of use.

[0059] At the same time, the provision of the locking spring 7 and the reset spring 8 enables the locking mechanism and the button 6 to have an automatic reset function, thereby improving the convenience and reliability of operation.

[0060] In addition, compared with the traditional technology, the brewing component 4 is an independent module, which is easy to disassemble and install. When cleaning the equipment, only the brewing component mechanism needs to be disassembled, and the main body with the motor mechanism is fixed in the coffee machine without disassembly. Therefore, the brewing component can be disassembled and cleaned at will, and can be directly installed and used after cleaning without adding grease and other operations, which greatly reduces the workload of users. In addition, the brewing component is small in size and can be directly rinsed or placed in a dishwasher for cleaning, which reduces the labor cost of the later use of the coffee machine. If the brewing component 4 is damaged or needs to be replaced, the user can directly replace the module without repairing the entire coffee machine, which reduces the maintenance cost, so it can be widely promoted and used.

[0061] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
