Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a connection locking mechanism between a brewing device and a coffee machine. Background Art

[0002] A coffee machine is an automated electrical device used to make coffee of various flavors. It uses different technologies and principles to mix ground coffee beans with water or other ingredients through heating and pressurization to make different types of coffee drinks, such as espresso, Americano, latte or cappuccino.

[0003] The main components of a coffee machine usually include: Grinder: used to grind coffee beans into powder. Some high-end coffee machines have adjustable grind settings, allowing users to adjust the coarseness of the grind according to the type of coffee and personal taste; Boiler or heating element: used to heat water to a suitable temperature for making coffee; Brewing device: responsible for passing hot water or steam through the coffee powder to extract the flavor and aroma of the coffee; Filter or filter: used to hold the coffee powder and prevent it from entering the final coffee drink; Control system: includes buttons, touch screens and other user interfaces for selecting parameters such as coffee type, strength, cup size, etc.

[0004] At present, the brewing device, as the core mechanism of the coffee machine, generally has a very complex internal structure; and this structure also plays a decisive role in the taste of the brewed coffee; for the sake of simplicity of the structural solution, the existing coffee machine usually integrates the brewing device with the main frame of the coffee machine. In these technical solutions, since the brewing device is fixed in the coffee machine, the user cannot take out the brewing core component for cleaning separately, so that after long-term operation, the internal pipeline is blocked due to the failure to clean the coffee or coffee powder residue remaining in the brewing core component in time, which will directly affect the final taste of the coffee: and since the user cannot effectively clean the inside of the brewing core component, the coffee powder residue remaining in the brewing cavity will also become moldy, which will not only affect the taste of the coffee, but also pollute the brewing cavity.

[0005] Based on this, Chinese patent CN101621947B discloses a detachable infusion unit for producing hot beverages, especially coffee, comprising: a support structure mechanically connected to an infusion chamber, the infusion chamber comprising a first part and a second part movable relative to each other; and a mechanism for opening and closing the infusion chamber. The support structure and the opening and closing mechanism of the infusion chamber are made of a material that does not require external lubrication.

[0006] However, the connection structure between the brewing device and the coffee machine disclosed in the prior art still has the defects of complex operation and relatively poor reliability. Specifically, in the technical solution of the existing detachable or separable brewing device, it is locked with the main body of the coffee machine by using a hidden hole shaft. In this connection method, the hidden hole shaft is not conducive to the user to perform operations such as unlocking, and there is a defect of complex operation; and because the brewing device is a reciprocating action, it will generate greater pressure when working; the reciprocating action and other factors make the connection method such as the latch not reliable enough, and it is easy to cause the latch to fall off and make the connection between the brewing device and the coffee machine invalid.

[0026] Please also read Figures 1 to 3 The present invention provides a connection locking mechanism between a brewing device and a coffee machine, comprising: a main frame 1, a brewing device 2, a locking portion 3, a clamping portion 4 and an unlocking portion 5; the brewing device 2 is movably accommodated in the main frame 1, the locking portion 3 is movably connected to the main frame 1, the clamping portion 4 is connected to the brewing device 2, and the locking portion 3 is movably connected to the clamping portion 4; the unlocking portion 5 is movably connected to the brewing device 2, and the unlocking portion 5 is movably connected to the locking portion 3.

[0027] Specifically, the main frame 1 is usually the main frame of the coffee machine, and the brewing device 2 is arranged therein; and when the brewing device 2 needs to be locked and connected with the main frame 1, the user puts the brewing device 2 into the main frame 1 so that the locking portion 3 provided in the main frame 1 clamps the clamping portion 4 provided in the brewing device 2; at this time, the locking portion 3 and the clamping portion 4 are mutually clamped, so that the brewing device 2 is restricted in the main frame 1. Thereafter, when the main frame 1 and the brewing device 2 need to be locked in contact, the user needs to press the unlocking portion 5 provided in the brewing device 2 so that the end of the unlocking portion 5 touches the locking portion 3, and then the locking portion 3 leaves the clamping portion 4; at this time, the user can take the brewing device 2 away from the main frame 1. It can be seen that the connection locking mechanism between the brewing device and the coffee machine of the present invention proposes a structural scheme that can conveniently achieve the locking and unlocking states. When locked, the locking portion 3 can maintain the mutually locked state with the clamping portion 4 until the user manually triggers the unlocking portion 5 to release the connection between the locking portion 3 and the clamping portion 4; thereby, the connection reliability between the brewing device and the coffee machine is improved.

[0028] Furthermore, the main frame 1 has a frame structure 101, a lock accommodating chamber 102 and a brewing accommodating chamber 103; the lock accommodating chamber 102 and the brewing accommodating chamber 103 are adjacently arranged in the frame structure 101; the lock portion 3 is movably connected to the lock accommodating chamber 102, and the brewing device 2 is movably connected to the brewing accommodating chamber 103.

[0029] Furthermore, the locking portion 3 has a swinging body 301, a torsion spring 302 and a locking hook 303; the swinging body 301 is movably connected to the locking accommodating cavity 102, and the torsion spring 302 respectively connects the locking accommodating cavity 102 and the swinging body 301; the adjacent side of the swinging body 301 is connected to the locking hook 303, and the locking hook 303 is movably connected to the clamping portion 4.

[0030] Furthermore, the brewing device 2 has a brewing body 201 and a handle 202 ; the brewing body 201 is movably connected to the brewing accommodating cavity 103 , the clamping portion 4 is arranged on the adjacent side of the brewing body 201 , and the handle 202 is arranged on the side of the brewing body 201 .

[0031] Furthermore, the unlocking part 5 has a pin shaft 501, a pressing part 502 and a spring 503; the pin shaft 501 is movably inserted into the brewing body 201, one end of the pin shaft 501 is movably abutted against the swinging body 301, and the other end of the pin shaft 501 is connected to the pressing part 502; the pressing part 502 is arranged adjacent to the handle 202, and the spring 503 is arranged between the pressing part 502 and the brewing body 201, and the spring 503 is sleeved on the pin shaft 501.

[0032] Specifically, the swing body 301 can be movably connected around the connection between it and the lock receiving chamber 102, thereby realizing a reciprocating swinging action state; and the torsion spring 302 serves as the power for the swing body 301 to reset. More specifically, when the user puts the brewing body 201 into the brewing receiving chamber 103, the clamping part 4 arranged on the side of the brewing body 301 can just be mutually buckled with the lock hook 303. At this time, the torsion spring 302 maintains the posture of the swing body 301 unchanged through the elastic force, thereby enabling the lock hook 303 arranged on the side of the swing body 301 to firmly maintain the connection state with the clamping part 4. Thereafter, when the user needs to unlock, he only needs to hold the handle 202 by hand, and then press the pressing part 502 with the thumb or other hands or fingers, so that the pressing part 502 pushes the pin shaft 501 along the penetration point between the pin shaft 501 and the brewing body 201, and then, one end of the pin shaft 501 abuts against and pushes the swing body 301, so that the swing body 301 drives the locking hook 303 to move, and then, the locking hook 303 leaves the position of the clamping part 4; thereafter, the user pulls the handle 202 by hand to remove the brewing body 201 from the brewing accommodating cavity 103. Thereafter, if the user removes the force on the pressing part 502, the various components can be reset, and at this time, when the brewing body 201 is placed in the brewing accommodating cavity 103, the locking hook 303 can complete the fastening connection with the clamping part 4.

[0033] For further information, please refer to Figure 4 The clamping portion 4 has a clamping extension portion 401, a lock hook limiting portion 402 and a lock hook guiding portion 403; the clamping extension portion 401 is connected to the side of the brewing body 201, the lock hook limiting portion 402 is arranged on the clamping extension portion 401, and the lock hook guiding portion 403 is arranged on the adjacent side of the lock hook limiting portion 402.

[0034] Furthermore, the lock accommodating cavity 102 has a lock cavity 102a, a lock hook stop portion 102b and an opening structure 102c; the lock hook stop portion 102b is arranged on the side of the lock cavity 102a, and the lock hook stop portion 102b is movably connected to the lock hook 303; the opening structure 102c is arranged on the side of the lock cavity 102a, and the clamping portion 4 is movably connected to the opening structure 102c.

[0035] Specifically, when the user puts the brewing device 2 into the main frame 1, the clamping part 4 can enter the interior of the locking cavity 102a from the opening structure 102c, so that the clamping part 4 is ready to be movably connected with the locking part 3; the locking hook guide part 403 provided on the front end side of the locking hook limiting part 402 can generally be a slope structure. In the process of locking, when the locking hook 303 abuts against the locking hook guide part 403, the locking hook 303 can slide upward along the slope, thereby making the swing body 301 overcome the elastic force of the torsion spring 302 and swing counterclockwise, until the locking hook 303 leaves the guidance of the locking hook guide part 403, and the torsion spring 302 recovers its deformation to drive the swing body 301 to swing clockwise, and then the locking hook 303 and the locking hook limiting part 402 form an interlocking and locking state.

[0036] Furthermore, the lock hook stop portion 102b provided in the lock buckle accommodating cavity 102 can serve as a stop structure for the action of the lock hook 303 to prevent the lock hook 303 from swinging excessively and deviating from its preset action position when the torsion spring 302 pulls the swing body 301.

[0037] For further information, please refer to Figure 5 and Figure 6 The pin shaft 501 has a shaft body 501a, a rotation stopper 501b and a rotation limiting portion 501c; the rotation stopper 501b is arranged in the shaft body 501a, the rotation limiting portion 501c is arranged at one end of the shaft body 501a, and the pressing portion 502 is arranged at the other end of the shaft body 501a relative to the rotation limiting portion 501c; the rotation limiting portion 501c is movably connected to the swinging body 301, and the rotation stopper 501b is arranged between the pressing portion 502 and the rotation limiting portion 501c.

[0038] Furthermore, the brewing body 201 is provided with a main structure 201a, a screw-in guide limit hole 201b and a square limit hole 201c; the screw-in guide limit hole 201b and the square limit hole 201c are relatively arranged in the main structure 201a; the screw-in guide limit hole 201b is movably connected to the rotating stopper 501b, and the square limit hole 201c is movably connected to the rotating limit part 501c.

[0039] Specifically, when the pin shaft 501 needs to be assembled in the brewing body 201, the shaft body 501a can be first inserted into the screw-in guide limit hole 201b from the entrance according to the preset position and pass through the screw-in guide limit hole 201b, so that the rotation block 501b can just pass through the cavity of the selected screw-in guide limit hole 201b; thereafter, the shaft body 501a is rotated to rotate around its own central axis by a preset angle, at which time the rotation block 501b just staggers the position of the screw-in guide limit hole 201b intersecting the cavity; the shaft body 501a is then continued to be inserted so that the rotation limit part 501c can just be inserted into and limited in the square limit hole 201c; at this time, one side of the rotation block 501b movably abuts against the cavity on the inner side of the screw-in guide limit hole 201b. At the exit of the screw-in guide limit hole 201b, at this time, the rotating stopper 501b will be blocked at the exit of the screw-in guide limit hole 201b due to the offset of the insertion cavity channel of the screw-in guide limit hole 201b; at the same time, the rotation limit part 501c is partially inserted into the square limit hole 201c; thereby, the shaft body 501a can no longer be rotated around its axis, but can still reciprocate along the direction of its axis, and the rotating stopper 501b can be blocked on the inner side of the screw-in guide limit hole 201b; thereafter, the user can conveniently press the pressing part 502 to make the pin 501 move inward so that the rotating limit part 501c can abut against the swinging body 301, while the shaft body 501a will not accidentally detach from the brewing body 201 due to the blocking of the rotating stopper 501b.

[0040] In summary, the connection locking mechanism of a brewing device and a coffee machine of the present invention is respectively provided with a main frame 1, a brewing device 2, a locking part 3, a clamping part 4 and an unlocking part 5; the brewing device 2 is movably accommodated in the main frame 1, the locking part 3 is movably connected to the main frame 1, the clamping part 4 is connected to the brewing device 2, and the locking part 3 is movably connected to the clamping part 4; the unlocking part 5 is movably connected to the brewing device 2, and the unlocking part 5 is movably connected to the locking part 3. The connection locking mechanism of a brewing device and a coffee machine of the present invention proposes a structural scheme that can conveniently realize the locking and unlocking states. When locked, the locking part 3 can maintain the mutually locked state with the clamping part 4 until the user manually triggers the unlocking part 5 to release the connection state of the locking part 3 with the clamping part 4; thereby, the connection reliability of the brewing device and the coffee machine is improved. Therefore, the connection locking mechanism of a brewing device and a coffee machine of the present invention solves the technical problem of how to improve the convenience and reliability of the connection between the brewing device and the coffee machine.
